Sites like Cookening, EatWith, and MealSharing are to restaurants what Airbnb is to hotels. Sign up as a host to earn dough by cooking and serving meals to guests in your home. It's up to you what you want to cook and how many people you can accommodate. Cooks are paid directly through the site, so no cash ever changes hands. The earning potential for becoming a cooking host is $50-$100 per meal.
If you have deep knowledge of one or more subjects, you can make money teaching online, such as at a site like Udemy.com. Some instructors there are making a lot of money, but many are just making a few thousand dollars a year -- or less. Still, even that can be very helpful. The money you'll make will depend on how many students take your course, which will depend, to some degree, on how in-demand a topic it is, and how well marketed it is. Note that once you do the work to create a course, you can most likely re-use much or all of it later.
Sign up for a reputable affiliate network: Aside from Amazon, there are dozens of top affiliate programs for bloggers and even large reputable affiliate networks, such as Share-A-Sale, Clickbank, and Skimlinks, that specialize in connecting you with merchants who are looking for affiliates to sell their products. They charge relatively low commission fees for the privilege of connecting you with merchants, and the merchants on these sites tend to offer much higher commission percentages or set dollar amount payouts.
Socialize. Especially when you’re getting started, you need to establish contacts who are already immersed in the business. They can act as mentors, keep you up to date on industry changes, and even help you land your first or subsequent job. Look for the local chapter of the Association for Healthcare Documentation Integrity (AHDI) in your area and join.
How many email newsletters are you bombarded with every single day? There’s a reason for that. Email marketing to an actively interested group of email subscribers is one of the best ways to make money online. There have even been million-dollar businesses built from simple email newsletters like TheSkimm, or Mister Spoils. Each newsletter targets a specific type of user with interesting, daily content, while also partnering with relevant companies and affiliates to bring in extra money. If this seems daunting, it’s not. Email marketing tools like MailChimp, ConvertKit, HubSpot and AWeber make it easier than ever to get started with email marketing. Here's my comparison of ConvertKit vs AWeber vs Mailchimp to review a few of my top picks. And another great option to consider (with the largest free plan available) is SendPulse, with their ability to send up to 15,000 emails per month to 2,500 subscribers, and then affordable plans starting at under $10/month as you grow from there.
Companies like Uber and Lyft offer a great opportunity to make some quick cash. You'll need a clean driving record, a fairly new car and the authorization to work wherever it is that you live. If you have all of those things, you can work when it's feasible for you, whether that's in the middle of the day during rush hour, or in the wee hours of the night on a weekend. The choice is yours.
