Ask HN: Freelancing in the Bay Area

I'm interested in doing freelance web development work in the SF/Berkeley bay area, and was hoping some of you could share your experiences and advice.

I fully expect it to be more work than a full-time position in a tech company, and that I will have to delve more into the business side of things.

However, my concerns are about the types of freelance opportunities in the area, and if most are wordpress type jobs. Is front-end javascript and iOS development relegated to full-time positions?

I have a CS background and worked full-time for some time, but quit to work on my own projects instead. I've found some part time work improving a Meteor app, and am liking working this way much more. I'd like to take it to the next step, where I can work mostly on client projects and work on my own projects as well.

I'd appreciate any insights and advice. Thank you.
