Well there's the Resource Requests and Third-Party Services section of this forum. From my limited experience there's not exactly an ample supply of coders just waiting for work. The coders who know what they are doing are busy on their own projects and most admins don't want to pay for the learning curve of a coder who doesn't know what they are doing wrt XF.
I see. My point is that such a list could be very helpful, I've seen many threads where coders are wanted for payed projects - and there are few takers. But you are probably correct in your assumption that skilled coders already are busy with ongoing projects, all the time. I'd better get in line then
