Just start building stuff (anything) using your existing skills. As you run into "how do I do that" style questions, fill in your knowledge. The benefit of this is that you're able to apply what you know to solve real problems. Big difference when all you're doing is studying theory/books.

Spend six months building stuff and you'll also have a decent portfolio that's inline with your current skill set. Winning freelance work can be a "show don't tell" sort of arena, so having any work helps.
