Someone should also tell you that getting to the big Tahr and Red dear means some serious Apline hiking and climbing.'
You can legally (unless it's changed) hire a helicopter to get you up to elevation, drop you in, and help you get everything out. Outfitters handle those details usually but I think even some of them will "Outfit you" for an unguided hunt.
Had a great buddy down there that was an outfitter for many years but we lost him a few years ago. He did a lot of those kinds of hunts for people.
Also, don't forget the trout fishing, if you skip it you'll hate yourself.
