Live WebChat Cam Site

We are looking to create a Live video camera site. It should have all the same features and workflow of [login to view URL] The site will have multiple public chat rooms where customers can tip with tokens. These tokens can be purchased through the website once the customer creates an account and logs in. We would like the website to accept these payments through the user's choice of payment processors. The site should have a full administration page where the owners can configure things like payment gateways, price per token, and more. We would like the application to be written in php and able to be run on a linux web server and use a mysql database for the back end. We would like the public chat rooms to allow up to 5000 people, possibly more, in them at a time. We would like the video chat software to be written in either flash or java and not require any installation on either end and support h.264 cameras as well as standard web cameras. For an excellent example of what we are looking for, go to www.myfreecams.com. We will have more opportunities in the future developing mobile apps to integrate with the website.
