Let me get this straight, you don't have a game yet, but you want authors (programmers) to make games and then testers for these games?
I'm failing to see how this thread is going to help you. I would suggest that you clarify exactly what technical positions you need filled, what kind of project you are wanting to work on, and when you plan to start.
Also, as was pointed out, there is no need to ask for testers unless you have a game that is already in development and has areas which can be played (tested).
