adult webcam chat solution/script

I currently have an adult site that i need to add a webcam/chat feature. I don't need the feature to have a timer. the simple idea client has: users logs into site, purchases a package, ($40 for 30 min of chatting) owner of the site is notified as well as the model that is picked while picking the package. the model logs into her chat room as the ADMIN of her chat room, user logs in as well.. and the chat begins the model takes care of keeping time. if you have a script solution that we can buy and you just install to the site I prefer this. If you find a solution with a timer even better but it is not required. site is already designed and setup. just need to add this script. site is in HTML but possibly might be in wordpress when you work on it. place private message me with your solution. thanks.
