Sorry to hear about your job. This sounds like what happened to a lot of teachers here in the Atlanta area. Your not in the Atlanta area are you?
Anyway, I don't know if this would help, but this opportunity is very part-time meaning it's not something you would do all of the time. The opportunities come up every couple of months and then you decide if you want to do it or not based on your current schedule. But it's grading essays and short compositions for Pearson online. You could possibly grade anywhere from middle to high school, depending on what you put on your application. I think you could also grade math if you have a degree in math. But they will guide you on the application.
Here is a link. On the bottom left, you'll see a menu, click on Scoring At Home. You'll find more info there. Let me know if you have any questions. I'm actually on my second assignment with them right now.
Good luck to you.
