how to use the fb page for making money?!

I got facebook page whit 52.000 likes (not really active, but i can fix it)
what is best to do in this case, how to get a profit, and whether it's possible to do it at all?
BTW the site was founded in the sense of fans of metal music..
What are your suggestions?

It’s hard to fix pages that aren’t very active, I had one with 60k fans, was very active and then didn’t post for 6 months and I hardly got reach after that, but good luck, I’d say post shareable images to see if it can get active again.
