Perhaps partnering with a paysite and doing cross-linking would be a good start, especially for someone who handles their own Customer Service (as opposed to a CCBill or Epoch situation etc).
It's not a bad idea but you would have to work out the ROI since there are so many factors. This is why a service was suggested, because then you could "work" many different paysites and affiliate programs. Kind of like how review sites work.
(Actually, how about using some of your girls for 'live reviews'? Now THERE'S an idea!!! Great mainstream marketing potential, too. Do a half-hour video for YouTube where you show the girl in bikinis etc looking at a blurred-out monitor and describing what they see and how great that site is. With some tweaking it could rock.)
