I made a pony adopt but I don't know much about pricing
This is the pony: sta.sh/0xtkrwapjtq

I don't know how to sell her, whether I should put her on offer to adopt, set price or auction
Which method would earn most?

If auction, what do you think would be a good starting bid and auto buy

If set price, how should I price it?
If by time, it would cost $10
But that's way too much isn't it?

How do you think I should sell?
