I have a FB page with 350k organic likes/followers…

Like the title says, I have a FB page I created about 6 years ago. I haven't posted in 4 years. It still grows very slowly. I would like to either sell it (although it seems like there are too many scammers to dig through to legitimately do this) or attempt to monetize it. It was based off something viral at the time so I believe more viral content would keep the page growing.

Any advice would be greatly appreciated. Thank you.
