Also a lot of universities have "student job services" where you can find daily jobs - like helping with a move or something. I don't think McDonalds employs people for just 40 hours?
If there is no such student job market yet in your city, start one - I would be interested to help.
You could probably do a few odd jobs on RentACoder, Elane or something similar. Don't have much experience with them.
Do you happen to have any experience with Facebook Applications? I'm looking to outsource a small Facebook App, if you have any experience there feel free to drop me an email (edanm@btlms.com).
