hey scott,
thanks for your message; total costs are hard to tell, especially the gear is expensive, if you have to buy this from scratch it can cost you between $1000 and $3000, depening on your choice and wishes. And ofcourse if you already have some stuff...
If you join a guided group you do no have to buy stuff like tents, ropes, stoves etc.
Flights are ofcourse totally dependent on where you coming from, but from most places in the world you should be able to get to argentina or chili for about $1000-$1400 max
Permit is max 300 depending on the dates.
I cannot be more specific I am afraid.

good luck and keep climbing,
Harry
