This depends on what you want to sell. If you want to sell clothing items or other things with your own designs on them, you could start with a print on demand site like Zazzle or Redbubble where you provide the design and the vendor prints the product to fulfill orders. You will get only a percentage of the profit, but you do not need to pay anything up front or to keep your digital store open on these sites. If you are making a physical product and are looking for free or cheap raw materials, try garage sales or Craigslist. For example, you may be able to get free lumber that someone is looking to get rid of.
Waiting tables and bartending are good ways to make extra money, but it’s not exactly if the work was easy. And if you don’t have any experience good luck applying at the nicest place in town, most restaurants require experience. Also if you have problems dealing with demanding, hungry people – STAY AWAY! The hours are late, sometimes you won’t make any money. Especially right now, starting at new place will be difficult, if you can get hired expect to be the first one cut every night (aka less money) as those with seniority will want to stay. It still is a good deal though. I’ve put myself through college (chem major) without loans, never lived in the dorms, and I have about 10K in the bank. I will continue working in the restaurant biz even after I have a “Real Job,” the extra 10-15K/year for part time work is worth it.
People often have very unique reasons for wanting to start a blog and make money from home. Some blogs, like this one (DollarSprout), are meant to be informative resources for readers. Other bloggers may opt to share personal sides of their lives. For instance, many people will start a blog to document their fitness journey and inspire others along the way.
You can do a lot of things, like selling old study or work books on eBay. You could look into having a yard sale and sell old toys, shoes, and clothes. You could have a bake sale or lemonade stand, but to make it stand out, add a twist like blackberry mint lemonade or lemon curd sunshine. If you are creative with it, you can attract more customers.
Do you constantly come up with witty one-liners? Do you dream of the days of Mad Men-style advertising? If you’ve got some branding chops or just come up with imaginative copy, there are lots of opportunities to make money online through company naming and slogan contests. If you think you have a knack for names check out the Squadhelp platform where you can earn a little extra money online by naming brands, services, products, company slogans and even help out on the logo design front if you've got the chops.

While we all have some extra time, it often doesn't feel like it. But it also doesn't take too much effort to make some extra dough on the side. We're not talking about millions upon millions here -- we're mostly talking about doing small, bite-sized projects to generate some fast cash. And depending on your skill set, you could easily make a few hundred dollars or even a few extra thousand per month. 
Selling blood….there are very few companies that buy your blood. #1 reason being MANY people willing to sell their blood are not the type of people you want to receive their blood, ie drug addicts (not everyone). And if you can find a company willing to buy your blood you can only give it every 56 days (for whole bood). The most common blood product that is bought is plasma and you can only do that every 28 days (in New York state …which won’t buy blood anyways).

The truth of it is that it is going to be hard to compete unless you offer something good or tug at the heart strings. Many commercial car washes can do a full wash for $5 in just minutes, and it's going to be hard to compete with that. But, there are a few ways you can still manage. Teens to mid twenties work best. Be sure to have some buff looking guys and girls to enthuse the car owners to stop (yes, it isn't ideal but it works). Advertise everywhere -- throw flyers out from a plane if you have to. Donate a portion of the profits to charity. And advertise this really well. And be sure to stick to your wording and donate said portion of the profits, not a portion of the income.
BigCommerce is a turn-key solution for online entrepreneurs that gives you a number of built-in features, including several marketing options that allow you to find (and woo) your target customers.

Here’s a good example of how lead sales can work in real life: My second website, Life Insurance by Jeff, brings in a ton of traffic from people who are searching the web to find answers to life insurance questions. While I used to have the website set up so I could sell these people life insurance myself, it was a lot of work to process all the different requests and clients. As a result, I started selling the leads I gathered instead.
Equipment. The largest, and most important, piece of equipment that you’ll need is a high-quality sewing machine. They can range in price from about $2,000 up to $6,000, and you’ll want the best one that you can afford. Other pieces of equipment will vary, depending on what you want to specialize in. For instance, if you intend to make custom draperies, you’ll need a serger, and a drapery steamer.

In my (unpopular) opinion, getting a raise is harder than getting a promotion. Think about it from your boss’s perspective, would you rather a) pay more money for the same service, or b) pay more money for additional responsibilities. Alas, if you feel you’re overdue a raise, check out Dr. Randall Hansen’s article on Getting the Raise You Deserve. There are some really useful strategies there.

Do you have a ton of followers on your personal Instagram, Twitter, or any other social media? You can leverage those followers into cash dollars. “Influencer Marketing” is becoming really popular these days as brands are looking for more authentic ways to connect with their target audience. Check out this (free) Step-By-Step Guide To Becoming An Influencer In Your Industry.

As you start regularly putting out content, you’ll hopefully start to build a bit of an audience. But to start seeing real money from YouTube you need to market your videos elsewhere. Share your channel on Twitter and Facebook. Distribute videos anywhere else you can think of. Also, interact with comments and build a community around the videos you’re making so people will share it with their friends.
I know starting a blog is a way to make extra money.  I just wish it was not take so much time it is not easy. To come up with new things to write about plus getting the traffic to your site. Just like your list here no way you just set down and wrote this all at once it took a lot of research and searching your brain.  Great info and thanks for taking the time to put it all together.
@moxie1956 Thanks for sharing your experience with CashCrate.com. That’s certainly disappointing to hear that you weren’t able to make the $50-$75 a month that I expect. Maybe they are just going through a seasonal downturn or something. Like I mention above though, the real money with Cash Crate comes in the referrals. Find a way to consistently refer a large amount of people to the site.

The hardest part in making extra money is always the FIRST STEP in how you can earn extra cash. These tips will serve as a spark for those who are really confused where and when they should start with this financial journey. Making money is not all about intelligence, it is all about making your intellect work for you to have money. It is the wit-the “street-smart” style of approaching things.
One should think about their skills, hobbies and basic daily habits as well. Do you like to cook? Be a personal cook or dinner parties. Baking? Make wedding cakes or cupcakes for weddings/special events. Do you enjoy cleaning? Trying going to banks/repo companies and ask if they are in need of a repo cleaner or market yourself as a all-around cleaner. Know how to mow a lawn? Get paid to do it in your neighborhood. Sell products from large companies – Jewelry in a candle, Sentsy, Health and home products – etc.
With drop shipping, you’re effectively partnering with a manufacturer or wholesaler to sell their products. This way, you don’t pay upfront costs to buy inventory, aren’t sitting on unsold items taking up expensive warehouse space, and don’t have to deal with shipping the products yourself. You simply create your site, fill it with drop shippable products, and drive in customers, with almost everything else done for you.
It’s industry standard to charge anywhere from $1,000-$2,000 per month per client, and you don’t need previous website or marketing experience to get started. As you bring on more clients and build a reputation in your community for delivering outstanding results, your income can scale up quickly. It only takes a handful of clients to start building a full-time income.
Companies will pay you to virtually sit on mock juries to give attorneys and other jury consultants feedback on cases they are currently handling. Think of these as focus groups. The cases are real, but your verdict will do little more than give those involved a prediction of how things might go when it's time to go to court. You can earn fees ranging from $5 to $60. Be sure to read all the disclaimers and details. If this sounds interesting go to eJury.com or OnlineVerdict.com to find a case.
If I have a blog that is getting 100,000 page views a month that means that I’m probably getting at least 50,000 people to the site (most blogs will do between 1.2 to 1.4 pages per session). That means I have to try and get some small percentage of those people to buy something from me if I really want to do well. If I can’t get them to buy something then (in some cases) I have ads running on the site that will make me money anyways.
One of the best places to sell unwanted personal possessions is Decluttr, a website that buys used items directly from consumers. Unlike trade-in marketplaces such as Gazelle and auction websites such as eBay, Decluttr doesn’t act as a middleman between buyers and sellers. Rather, it’s best understood as a bulk buyer: an enterprise with deep pockets and an unsatiable appetite for used consumer products.
