Okay , I am a complete novice here but one idea might be to look at Uruguay. They are trying to establish themselves as a world center for IT and I have known of them hiring but I don't know about right now. Uruguay is MUCH more stable ecomically but if Argentina does indeed go into an economic crisis, as many expect, it will affect Uruguay as well. But it is still more stable in any case. Chile is also more stable and they hire IT people. You might should broaden your sights.
On Spanish I am sure you are a LOT younger than I. But I can't see being very proficient in Spanish in less than two years and that is probably not eough time. But maybe for some it would be. Not for me. One friend of mine who went to Uruguay hoping to find an IT job had many opportunities where they wanted him but without Spanish he was unable to get himself hired. That's what he heard everywhere. They wanted someone to speak English, and that was a plus, but also to speak Spanish..
