I think Ronnie's got most of it so far, the tour really needs some work and vid caps are always rough on surfers, member's area or no. If you can build up a member base then keep doing 20 hrs/wk for them you can probably retain exceptionally well.
Emmanuelle has offered her help and she specializes in niche sites, so I'd advise you to get in touch with her
I think you've got a lot of potential there, and I haven't seen too many fetish specialty camgirl sites thus far. You've just got some road between you and being able to really capitalize on it.
