Need a Facebook Group MASTER

Hello, I need someone who is a master at marketing on facebook groups. There are groups we want to post our links on but don't want to trigger spam filters or blacklist our domain. The ideal candidate needs to have a strategy to post on multiple groups multiple times with our business link that can be place in some sort of clocked dynamic url or intermediary landing page to protect our main domain that is running fb ads. We CANNOT risk our main domain.
