I need advice about voyer live shows basics
 

We are group of static websites owners. Recently we got request from one group (about 10 couples) who like performing live sex. They have experience with work for international studios but they often did not get paid therefore they wish to take all marketing in their hands. We told them this is not the thing we make and we feel it is not too much popular niche comparing to expenses. We suggested we can manage their content and create standard static websites and update them regularly if they create enough materials. But they refused. They told us they are real exhibitionists and they need to see reactions of people at the chat.

Because we want to help them we would like to know how it exactly works. Is there any suitable camera software which can immediately upload files to web server member area? And its client part which runs on surfers computer and downloads images/sounds for him? Or is the exchange of signal from performer to paying member realized other way?

And which billing providers are able to do 3rd Party solution? Or is there necessary to have own merchant account if they want accept credit cards? What if we create it as site with lots of static content and regular live broadcast as a bonus?

We welcome any single tip or suggests to create complete solution for us at suitable price.
