I need 8,000 facebook users to join a group to promote a music website. I'm paying $15. The selected provider will have to accomplish the target in 15-20 days. Whenever the group reaches 1,000 I'll release $2 until the end of the project. I'll pay extra if the group reaches more than 8,000.
Contact me for more details and for a link of the group.
Bidders with ratings and feedback are preferred. Everyone is welcome.
