Well... your site needs some work. You need a tour, you need to explain to people what they get if they buy - slapping a few pictures on a site and a big join button is not going to cut it.
If I was you, I'd go to the education center and read everything I could. Then look at how different paysites are designed, then look at how affiliates are promoting those paysites - then go back to your own and tweak.
Just to begin with. And welcome to GFY
