I am going to need a software for my solo models for the cam shows. and i want to be able to charge per minute or per view or whatever. most of the programs i see, it kind of entitles them to show our cam shows on their site too, i think. so i was thinking of making my own. i know a guy who can make the cam software, but how do you tie the paying method into the program

Or does anybody know any straight forward cam chat software, just for a solo girl site, so not multiple models or anything. i also want it so they can only view the model from my site and no other place. and i dont care to have other girls running when she isn't online or anything
