There's 1000s of cam sites online so it's definitely profitable. Whether it's worth your time is a different matter.. getting models onto your platform will be difficult for sure because all the top cam models want to be be on the big sites CB, MFC, LJ etc.... I would say if you don't already have models lined up to feature on the site it's probably not worth your time. Asian models from 3rd world countries could be worth looking into (indian, Thai etc..) as in most cases they will work for a lot less than your average western model, and there's a huge market for Asian girls but theres 100s of other Asian cam sites, so there's lots of competition. Other options could be to niche down and only cater for a specific fetish. I was looking into this myself few years ago but the competition was overwhelmingly and thought my time was better spent on other projects. But I wish you the best of luck!!
