“Donating plasma is similar to giving blood. A trained staff member called a phlebotomist puts a sterile needle in your arm vein to draw blood. The blood is then cycled through special, sterile equipment that separates plasma from the other parts of your blood. Your plasma is then collected in a container, while the other parts are safely returned to your body. This process is called plasmapheresis.”

…Marketing an eBook is definitely the hardest part. Ebooks have exploded in popularity and the market is unfortunately saturated with crap from people who thought they could write a quick eBook, put it on an affiliate network, and make millions. However, if you CAN find a good way to market (or possibly have others market by having it listed on affiliate networks) then an eBook can be a great way to make some residual income.

You'll also need ecommerce software, fulfillment software, worry about warehousing, customer service and refunds. But that's not all. You'll also need traffic. Think search engine optimization, Facebook ads, and other social media campaigns. It is hard work, especially on your own. You could opt for Amazon's platform, which might be an easier route. But, then again, at the end of the day, this is a serious business, which could produce significant profits. So you're either all in or you're not. 

Ecommerce is booming. While Amazon takes the lion's share, consumers are buying by the droves when they can scoop up great offers. In fact, some of the leading online marketers like Neil Patel, Frank Kern, Dean Graziosi, David Sharpe, John Reese and many others, are using free-plus-shipping ecommerce and book funnels to make small fortunes. This comes back to the implementation of sales funnels within an ecommerce environment. In fact, much of what people think about traditional ecommerce stores taking months or even years to build and costing a small fortune simply isn't true. 
 @Philip Taylor I was merely using medical science as an example profession. It’s quite obvious that you don’t have any professional courtesy and downplay professions in which you don’t understand. Logo design isn’t just logo design. I don’t know what the profession of a public accountant entails, or a lawyer perhaps, so I’m not going to give advice on matters that I don’t especially have knowledge in.
Disagree with the photography idea. It may seem easy but there are those of us who have spent, in my case 10 + years learning the light, the technical aspects, the right way to pose… we have to keep pushing our prices higher because there are more people starting to eat away at the client base by undercutting…. and we’re trying to make money and feed families too. It only hurts an industry to undercut. Sorry. Good list otherwise, don’t do it as an expense to others.
Note: There are dozens of other survey sites out there. These just happen to be the more well-known ones that have a reputation for paying out in a timely manner and having reasonable standards for cashing out. As always, be careful with your personal information. We recommend using an entirely separate email address for survey sites so they don’t clutter your inbox.
Let’s be honest. Those little people grow out of their clothes faster than you can keep up. When it’s time to get rid of the clothes they’ve outgrown, you have a few options. Put them out in your standard yard sale, sell them to a consignment store, or post them on social media. Apps like Kidizen are specially designed for selling your kid’s gently used threads. And of course, you can use other sites like Poshmark, thredUP, Craigslist and eBay to sell children’s clothing too.
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.
Skill. If you’re going to sew for other people, your skills need to be far above average. If you’re a beginner or an average seamstress, wait until you improve their skills before attempting to earn money in this type of business. If people are going to trust their wedding dresses or their favorite sports jacket to you, you must be able to handle them with care and the utmost skill.
Clearly, there's a lot of demand on Amazon, and if any product is going to sell, it's going to sell well on Amazon. But the goal here is to source the right products that will easily sell at the world's largest online retailer. Generally, products between $10 and $50 sell very well here. Just be sure to do the right market research before jumping on this bandwagon.
Word! Just because you aren’t a professional doesn’t mean you can’t have a good amount of talent in a subject. If you can provide quality services to people who can’t or don’t want to pay high professional prices, then go for it! That’s the free market right there. You have just as much right to try and make money for yourself and your family from your talents as professionals do.
Channel your inner minimalist and get rid of all those dusty DVDs or CDs on your entertainment stand or in boxes under your bed. And make the whole process easier with Decluttr. You can scan the bar codes of items you don’t want anymore and see how much money the company will give you. Instead of waiting around for a buyer to maybe purchase your item, the company itself will buy your items outright. See ya later, Godzilla DVD.
