Help with large fish Koi

I have several large Koi that have overgrown my pond. I want to replace them with some smaller ones but not sure what to do with the big ones? Sale them or give them away? Live in central valley of California and would like to see them go to a nice home.

Contact the central California koi society and ask if they have a a rescue program. Im pretty sure they do. http://cencalkoi.com/?page_id=8
