Hi, I need help for buy a new BB from Argentina!

I need someone's help to get 2 BlackBerrys and send me to Argentina. Have not arrived here yet and I already want to have them in my hands! Someone can tell me if this can be done, how and how much I would come out whole? I am looking for a 9900 and 9810, I hope someone can help me. And if this post right here, if not put him where he should go or let me know anything. Another thing, the band that we use here is the 1900 3G I think, so have to be AT & T, Bell or Rogers according to what I search.

PS: I am using a translator to post this so forgive the typos. Anyway I hope that is understandable!
