I mostly deal in free sites, but i'll tell you what I can since I just like to try and be helpful
AVS site is basically a mini paysite sorta. People by a membership through your AVS provider and gain access to your site along with whatever other sites are under the AVS provider.
Some AVS Providers are:
http://www.cyberage.com http://www.adultcheck.com
Hope that helps a little...I'm sure one of the AVS webmasters will hook ya up with a bit more info later on. Good Luck
