Any job suggestions that fit my hectic schedule?

I really need a job, but I live in a college town and the job availability is lacking. I go to class until 1 M-F, and attend night school for a different school from 7-9 M-F. On saturday and Sunday I am at the local childrens hospital volunteering with the kids with cancer patients, and it'd break my heart if I had to give my time with them up, and I know it'd break theirs as well. So basically I am free to work from 1-6 M-F. Any job ideas? Anything would help, I'm desperate.
