When I was in college I did about anything for money. I did stop short of prostitution, posing for porn and donating plasma for money. But two years running I had 5 different W2 forms, and there was other stuff besides like volunteering for medical experiments (I got $50!), digging ditches or doing about anything that called for physical brutality.
Now here's something called eMove from U-Haul. If you're over 18, you can volunteer to help people move at rates you set. You can pack/unpack, load/unload, drive, or whatever you can work out, and at rates you set. Or you can contact U-Haul to use these people.
It might be worth a look.
