YCH Animation Auctions? (Patreon)

So if I were to start doing auctions of a blank animation, with the intention of the winner of said auction telling me what character, OC or otherwise, they want in the place of the blank animation, would there be any interest?

It's so hard to gage how much things are worth myself, so I feel like having an auction could really help out

Also, give me some ideas of simple things I could start with.
I might just go through Patreon and Discord for suggestions regarding said YCH animations
