Hi Trish,
I will be arriving in SA at the start of October.
I will be in Buenos Aires until 14-15th of Oct and then I plan to go to Rio and work my way back down through Brazil, back into Argentina, heading to Patagonia. Hope to cross over into Chile and travel up to Santiago.
Let me know if that fits into your plans 
Paul
