Any recommendations on making ~$30/day with a few hours of work a day?

I've been working at OneSpace for the past about 2 years. It was pretty much the perfect arrangement for me, as I just needed a way to make about $250/week to keep me afloat while I went back to school.

We just got word a few days ago that the project I was working on is coming to an end. I am currently in the process of studying for the MCAT and getting a bunch of other things ready so I can apply to med school later this year, and I just really do not want the added stress/timesuck of looking for a brick and mortar job.

Any recommendations on jobs that will allow me to make about $30 a day putting in a max of maybe 5 hours each day? Preferably something that won't stress me out to the point of not feeling up to getting my studying done once I'm done making money for the day?

Thank you!
