As a parrot owner, I know that parrots need a LOT of attention, and generally tend to stick to one person. If you don't have the time to dedicate to a large bird, try a smaller one first.
If any bird, I recommend a Blue or White-Capped Pionus. White Capped have a better vocabulary then a Blue, but Blue are supposed to have a very docile nature. I can't say much about MY bird, he's anal to everyone but me, haha.
Don't pick a bird for looks, though. FInd a good breeder. Let them hand-raise the bird, but go back often to the bird you're purchasing and spend time with him before you take him home. Let him familiarize himself with you, and get to know you. It can take a while for a bird to really love you, though. So don't get discouraged if he nips every once in a while, and don't cage him up if he does.
If you do end up getting a large bird right off, remember that they CAN live quite a long time. The bigger the bird, the older they get, it seems.
Sorry I can't offer much else. I'm not quite sure what to say. But if you need supplies, such as toys, a great place to go would be the "Chirp 'n Squawk" website:
