whats the best way to find software development contract opportunities?

I like to start doing software development on a contract basis in San Jose CA. Whats the best way to go about getting started? Thanks for your insights!
I'd like to find opportunities in the bay area where I can take advantage of my ability to meet face to face with clients and help define requirements in person, something remote coders cannot do.

Like http://www.rentacoder.com, http://www.elance.com, http://www.getafreelancer.com and others. But I think it's very competitive with all the foreign workforce, so I don't know if that's what you're looking for.

The last week i gone through a web www.odesk.com
it seemed to be good for programmers that you can work on projects online.
you can bid for projects as well and get paid for hourly work.

hope it helps!
