I'd be very interested in both a subscription to such a site and the extra benefit of possibly "renting" her hair for real. I can only speak for myself of course, but I think $20 to $25 a month would be a bargain of a price for membership in such a site depending of course on the quality of material and if updates would be provided on a regular basis. As far as the live interaction part goes maybe $150 or $200 with the strict understanding of exactly the limitations. A personal "Hair Massage" only, no add ons or enhancements allowed.
Let us know if you'll be going ahead with the idea.
Thanks
