Hahahah I'm from chile and let me tell you, you will have a hard time, the accents here are hard to pick up and they are also very different from each other
Ski resorts to go: Valle nevado, El Colorado, Nevados de Chillan, Las Leñas, Bariloche, San martin de los Andes and Portillo.
I don't actually know about de prices but I would guess that the resorts near Santiago (Valle nevado, el Colorado and la Parva) are the cheapest, being el Colorado the cheapest one of those three.
It all comes down to what are you interested in, if you want to ski more powder than anything, then I would recommend Las Leñas or Nevados de Chillan, if you don't mind the snow and you would like to go to have a more broad trip (not just skiing related) then I would fly to Santiago.
If you need any help just shoot me a pm.
