I have done a bunch of work for single girl sites and one thing I would recommed is getting listed on cam portals like
http://www.camtracks.com . You need to make guys interested in her. Make it more personal so they feel like they want to get to know the girl better. That's what sells these sites. She can even do a public blog, post some softcore shots regularly...maybe even some softcore grabs from live cam shows so they can see what they'll get if they join. The site seems pretty hahahahahaha cutter right now. Make it a little more personal and I think you'll have a winner.
