i rehome ferrets and sell adults for £10 to £20
the odd time i have bred sold them for £15 silvers and £!0 for polecats if you are not willing to pay this ammount for an animal which could keep you in rabbits for the next 10 years then you wont get one
some sell the really dark polecats which do well at shows for £50
ferrets are under valued and should cost a lot more for good working stock
