I would be nervous working for someone I met on Craigslist. I've heard too many stories about Craigslist meet-ups gone wrong! I would want someone to come with me when I met the potential client, that's for sure.
While an opportunity is great, I don't want to advise you to settle looking for jobs at Craiglist. There are too many scams there that you can be wasting your time for a client. It's not the best platform for any freelance work.
