Do not go looking for a Baby (any) Parrot. There are far to many dishonest breeders out there that will send you home with a baby that is to young.
Start with your Certified Avian Vet (CAV). They commonly have several clients that are looking to rehome their Parrots. Also search for local rehome /rescue organizations as a source.
This will at least get your Thread bounced back-up the board and may catch someones eye.
May help to better define a bit more about the B&G you are looking for.
FYI: If it is your goal to mate this female new with your male, I would strongly recommend not proceeding down that path until you gather a ton more information.
