That's where I was-in the Andes, except I was living in the biggest city in Bolivia, not out in the boonies. Not sure how much things have changed since I was there (a long time ago), but once out of the cities, infrastructure is probably still lacking. I know you can find Internet cafes and such now in some places, but getting help in an emergency or expecting a chopper ride out if you are injured, as you probably know, is way too optimistic.

I'm not saying it can't be done, but if I was going on a long trip with newbie, the Peruvian Andes would not be the place I would go.
