Hey, sounds like CamZ may be able to help you out!
1) Studio setup is no problem. We'll create a studio account where you can track all individual performer sales and on top of that we'll give you 5% commission for their direct shows.
2) Setting up a site for them is a great idea. You can use our lobby option for your performer and choose from only certain niches to promote instead of just everyone who's online.
3) Our per minute charges start at $2.86 and go up. You/your performer can choose what price you want to charge. Non-US studios get 35% and as I mentioned above, the studio will receive and additional 5% commission on their direct shows (which means private shows from clients that you sent to the performer from her site or other area).
4) We allow solo, group, couple, whatever shows.
5) We are launching a new group show application where performers can make additional money. Will be running by the end of this month.
6) We offer:
Phone to Phone with 2-way Video
1 way Audio/Video shows
1 way Audio/Video shows with Phone
2 way Audio/Video shows
1 way Audio/Video shows with Controllable toy
7) We offer 2 flash broadcasting platforms that are very user-friendly and come with 24 hour tech support for setup, broadcasting, etc. Performer has control of banning/booting.
This is just a basic overview to answer your questions. I'm happy to speak with you anytime to go into more detail and answer any additional questions you may have!
