Bring real interested audience to new Facebook group

I need someone to bring new engaged users (with real authentic, unlocked FB profiles) to my Facebook group. I am looking for people who would engage. I am NOT aiming to have a countless number of spammy-looking accounts, who are never going to care what is going, join the group.
Quote your price for one day for now. But if I like the result, this could be a long-term ongoing project.
