I work on DataAnnotation. It can be tricky to get accepted but the pay is around $18+ an hour depending on the project. If you can code, the pay is closer to $30+ an hour. I can't code and my projects are all in the $20-25 range. I'm an elementary school teacher and I work evenings and weekends mostly or whenever I have some spare time! If you have typing and writing skills (good grammar, spelling, editing, etc.) it might be worth looking in to!
