You can also go with the " no paint " option, but Stainless Steel cages can get pricey rather quickly.
If you can swing it, I can recommend one of the Cages by Design setups. Though the larger sizes may be a bit outside of the $1200 range you are asking for I have had no issues with the cage for the past eleven years.
The only drawback is they are quite large so you'll need a spot big enough to accommodate them. Tic-Tac has lived in one
his whole life and it's held up very well.
Outside aviaries need some additional thought put into them based on where you live. If not Stainless Steel, they can potentially rust if exposed to moisture ( mine disintegrated after Hurricane Ike came roaring through ). Mosquitoes, stray cats / animals are also a consideration if you live in an area prone to them. The outside aviary would be best built with a standoff area between the inner and outer cage walls. This will prevent folks ( and cats ) from sticking their fingers / paws into the cage and either causing or receiving damage.
Also, even if she cannot fly, you'll be surprised how far she can get if the wind is blowing enough
Be careful during transitions periods from inside to outside.
