Video Chat money opportunity, question

I am in Romania, and I have to hire for a website 20 girls to videochat for him,
friendly dating videochat, now I also manage and develop for him the software solution with my company, and I thought this, make a package
deliver him the girls, manage the girls, and videochat messenger solution for a price per hour per girl, now I dont know exactly how much to charge, so I am waiting for opinions, girls plus software, a per hour fee is what I have in mind, from wich I will pay the girls soft team girls admins etc and hold a part for myself, what should this fee be?

Thanks
