Signups needed 8$ - Refferals needed

I need signups to this site: [login to view URL] People who signup need to complete an offer to validate the registration. I will only pay if: - the sign-ups are real people, with different ip addresses - the person completes the offer I'll pay you 8$ per valid registration, which means: if it is you that completes the offer --> you complete the worldwinner offer you will win 1$ but if you have a credit card you will win the whole 8$. if you recomend someone else --> you win the whole 8$. I will pay as soon as the registration is confirmed through paypal.
