Mechanical Turk is Amazon's take on micro-jobs. These are small miniscule-jobs that you can do for other people, which they call HITs, or Human Intelligence Tasks. These are super simple tasks that anyone can do. Some examples are listing off some URLs with certain kinds of images for one cent, or recording a few phrases with a microphone for 6 cents.

Furthermore, carefully consider your likely attendees, and what schedule would be attractive to them. For example, if you’re planning on teaching a tutoring class, you obviously couldn’t schedule it during school hours. Likewise, a class aimed at mothers of young children will either have to include babysitting services or be scheduled at night, when they’re more likely to have help with the kids. Find the delicate balance of times that fit your prospective students’ schedules as well as your own.

It doesn’t pay much, but if you’re a healthy person and want to make a bit of extra money online, the AchieveMint app will reward you for doing things like walking, tracking your food, or taking health surveys. AchieveMint works by connecting to fitness apps you might already be using like Fitbit, RunKeeper, Healthkit, and MyFitnessPal and then giving you points for certain actions. For every 10,000 points, you earn $10 with no limit on your earnings.
