A hack that worked for me when I was freelancing, was to put my resume on various job boards as if I were looking for full-time employment. When companies called me to set up interviews, I said (on the phone) "Turns out I decided I'm going to freelance. What was the project you wanted to interview me for? Perhaps I can help with that, as a freelancer." I got a lot of business that way and it pretty much started my career.
