Wanted: Older Female Cockatiel

I'm looking for an older female cockatiel to be a companion for my older male. My male is 10, looking for a female around that age (NOT a young female). I would prefer one that is tame but would settle for one that isn't mean. My male has had 2 mates in the past when he was with his previous owners, so I think he will bond with an older female, he is just very lonely and I would like to get him a companion. Willing to pay small rehoming fee so you make sure its going to a good home, but not willing to pay a lot, figure someone is probably wanted to give one away.
