I'm so glad to hear that you decided to get this bird. It always breaks my heart to see a bird in a pet shop that nobody seems to want for one reason or another. About the only thing I can tell you is that it's going to take A LOT of time a patience. How much time may depend on how old he is. Do you have any idea? I know you say your cramped for space but try and get him the biggest cage you can afford. I would say feed and care for him well and you should be good to go. There are MANY helpful topics covered in the "sticky library" that may also help as well.
