Need help rehoming two parrots in Seattle area

My mother is disabled and has 3 parrots. She is selling her house and needs to rehome 2 of her parrots as she downsizes her living space. The birds she needs to rehome are a female Cape Parrot named Hanna, and a male Illiger's Macaw named Indy. I believe Hanna is around 8 years old and Indy is around 5 years old. Both are in good health.

I am unfamiliar with parrot/bird forums, so I'm not sure where the best place to go to post ads for rehoming these birds. My mother has not been posting parrot forums in a few years, and she's not sure where to post either.

My mother did have someone lined up to buy Hanna after they met her a few years ago when my mom sold her Solomon Islands Eclectus to them. However, when she contacted them recently, they too said they are downsizing due to their own health concerns and cannot care for another parrot at this time. I saw that my mother was asking them $1,800 for Hanna and her cage. I don't know if that is a realistic number. I did some brief Googling and found people sell Cape Parrots for between $2,200-3,300 with no cage, so maybe it's a reasonable price. I don't know how much she wants for Indy, the Illiger's Macaw.
