5,000 Sign-Ups

I need 5,000 valid female fashion model and/or actress sign-ups to the free basic portfolio area of a fashion model portfolio hosting website service. It is a site for fashion models, fashion photographers and scouts/job providers to communicate and network for jobs in the industry. It's not a bad looking site and will done with being redesigned in a day or two. It is very easy to sign up and their e-mail will only be used for our newsletter. The main thing is I want is that all sign-ups are to be U.S. residents.
