Adult Content E-Commerce Site

I am looking for a website to sell adult content. I will need a shopping cart set up and possibly paypal. The front page will be the disclaimer to ENTER or LEAVE if they are not of age. The next page we would want to post some of our hottest items or new items. On the left would be all the genre's of video's we sell and toys and other stuff. I do not want a new window to open when they click on a genre. I also want to put one banner ad at the top, maybe 2, and have them change every couple of seconds.
