Adult Signups Required

I'm looking for people with Adult Traffic experience who can deliver Free Adult Sign-ups to an adult webcam site company. Sign ups need to be valid, with a valid credit card. No newsgroup or email spam, cheating, self signups, stolen credit card numbers etc. The web cam site is free to join but does require a credit card for age athentication. You will be paid $5 per free (valid) sign up. Will be looking at 20 sign ups per week, or just 4 sign ups per day over the course of 5 days. I will pay at the end of each week for each valid signup.
