I've found that the best way to freelance is via word of mouth. However, if you don't have a portfolio, what are your credentials? How do you plan to convince people you're worth hiring? You might want to work on a side project, it goes a long way towards showing people that you can actually build nice things.

Also, the startup I'm currently working on does something directly relevant, so you might be interested in updates: http://www.instahero.com/

I agree, do side projects until you can convince somebody to pay you for similar services.
