How to monetize this a/c. ?

Hi,

I have a 7 month old instagram harley quinn fan page(15k followers - all real)

My post get 1k- 8k likes and my post have 5-6k reach usually.

I was hoping if there is any way to monetize it.

I looked at ogads method but i didnt find anything that i can use on my a/c , ogads is for general niches.

I could surely use it, but in end its gonna hurt my a/c and get less reach as i will be posting non relevant content.

You could sell clothing related to her

see what your competition is doing
amazon affiliate may be the easy way out. cosplay costumes come to mind.
