I would add check the gigs & etc. section of craigslist to see if you can do focus groups. I also found a smallish part-time job on next door walking flyers for a real estate company around to people's houses. It's great exercise and I make a little extra money, even if it's not a lot.
Yes thank you for mentioning the gigs section. I know people who have found phone book delivery jobs on CL. They walk around to businesses all day just dropping off phone books.
