You're correct on what you've assume about the place (+ services) and for entry it may cost to 20$ to 80$US ticket entry depending on the event that will occur. It's quite the popular place so I advise to go around 2-3 am to enjoy what's beginning of things. So I advise you look at the events at their site and make a quick call on the price.
For me, seems like cover varies. Before midnight, I paid $20. Another night I came in after 2 am and paid $40. In a specific area they have a center stage where girls work the pole. They accept tips at whatever rate you want to give them. Private dances vary as well, some girls were offering $60/dance, but it could vary as well. Basically, the quality is worth the money, and be ready to spend a good amount.
