Promote my Social Site, Need 5k Members. Facebook, MySpace, Add Members to My Site, Need Traffic

I have a social networking site similar to Facebook or mySpace. I need to add minimum of 5k members to our site. Thus I need someone to add new members to my site, naturally or artificially. You can do it in several ways... 1. Promote our landing page 2. Manually upload members to our site 3. Create and promote through Facebook or MySpace. 3. Other method? Please PM your idea on how you would like to acheive this, and if it sound well planned I will give you a chance! I have perfect rating, I hope you do to. If not, we will use escrow or pay on deliver of service.
