When I talk to porn stars about quality sites I tend to refer them to like
www.NikkiBenz.com or
www.GinaLynn.com. Another one I like is
www.MorganDayne.com.
I think you need to be honest with her so that she fully understands what she is getting into and in doing that you need to let her know right away what kind of site you have in mind for her doing. Those three sites I just gave you are really top quality sites.
