No worries, I know all the freelancer sites but the quality over there is simply not acceptable. 99% india based companies where the business managers make the big money while the programmers code to get a part of that money (which doesn't really help them to be very interested in a project).
Looking for a professional is a different story and less risky if you choose somebody outside freelance portals

I do use scriptlance.com / rentacoder.com - but just for small things where nothing can go wrong (and sometimes it still goes wrong) lol
