Facebook groups bulk searching and post schedule

Hello everyone

I'm running a personalised sticker printing business and i'm thinking on moving to facebook groups to extend our customer base. My question is if there's any tool that can help me build a facebook group list base on different hobbies ( e.g. fishing , motocycle owners , camping fans and so on ) and schedule the posts for the groups aswell.

Interested
