Go for it, you just need a bit of patience in the beginning, but if you comminicate well in your proposal (provide some rough ideas about possible implementations, related experience, etc.) you stand a good chance of getting work. Once you get a few good reviews you stand a better chance that you will be invited to work without having to apply directly as well.
