Donating or selling breastmilk

Where have you contacted? I selfishly want to sell it. Almost a yr exclusively pumping only. I think i earn a few bucks. If not, that is fine. Problem is that i have super high lipase. Like when i would mix the last pump into something for baby. He won’t take it. Why???? Cuz you can taste the iron taste. It would be nice to know it can go to tubie babies
