I don't know about p2w, but you can use tebex to sell your in-game packs.

Ok I would use Tebex, and about P2W, I would personally sell ranks that gives you keys. It’s not really P2W if your not making any money off of it and giving it to the server. Yeah but just sell ranks for under $10. I would personally just help you if you need and you need to make private mines with those ranks. Maybe suffixes with those ranks.
