I think you should go with the long text pages, instead of a normal styled tour.
Something like [URL=http://milfhunter.com/main.htmMILF Hunter[/URL] or
Her First Gang Bang.
Your sample videos should be quality. You can keep 'em short, but the quality has to be nice. Who wants to join a video site with shitty video, right?
Anyways, Good luck!
