are you sure you want a webcam software which you can pay per minute. AFAIK, there is nothing pay per minute for a webcam software. If you are asking for a webcams program, webcams.com, camscash.com and plenty more are there.

Obviously he doesn't know how? And doesn't want to spend weeks doing it? Anyways. I have one, but I can't think of the name right now. It was one of the original ones years ago, I'm sure there are dozens if not hundreds out there now.
