Replying to Argentina Trip

Me and one of my buddies are trying to go to Bariloche for the month of August this summer and are trying to do everything dirt cheap, I know there are a few of these threads floating around but I couldn't find one with actually good info but if its there just hit me up with a link. 

Has anyone done this before and give me an estimate of what to expect to pay, as of right now were thinking around $3,000 for the whole trip all tickets included?

Also can anyone give me info on the hostel scene there or recommend a cheap place to stay, were really looking for the most gutta of gutta so suggest anything?

Lastly anybody seriously looking to do this trip who would potentially want to split housing or something like that hit me up as well but only if you're actually serious?

Thanks errybody appreciate anything ya can give me here
