I would think the average guided hunt is in the $5000-$6000 range. That's what it was when I priced it out at several places.
I ended up DIY and never went back, though I did have a local contact who helped me out the first year out there. Sure, my 6X6 only scored 243 and I came up empty the second year, but I took a lot more pride showing up at the truck with that rack on my back after an 8 mile hike out than I would have with a point-and-shoot guided hunt. We hunted, it wasn't just shooting!
