I'm looking to earn a little extra money after work and on weekends. What are some good part-time jobs?

I have a car and I have a computer at home and I live in the San Francisco Bay Area. Ideally it would be cool to do some sort of editing or something on the computer (Word, Excel, Internet) that would be cool. If I could use my car somehow that would work, too. I'm thinking of working maybe 5 - 10 hours a week or so. I need to bring in a little extra cash for paying for some counseling I'm getting.
