Looking for free unwanted birds and cages (Cresson)

Looking to expand my tiny aviary, we have 2 9 month old males a budgerigar and a green cheek conure and an avian vet and we are looking to take in older tame birds like African Grey's, hyacinth macaws, and Amazon's and cockatiels.
We are looking for free unwanted birds and free unused unwanted perches and cages.
We will take every bird we get to the vet.
