Josh will steer you right. Definitely look at Matt Snyder and the Enstminger's in the TMA.
A couple of things to ponder. Do you want to hunt with a small operation and talk to your guide all year leading up to the hunt? Are you OK with being assigned a guide when you get to camp? I'm not judging either setup. You can get a top end hunt with either scenario.
Are you good with a legal ram, or do you want something older/perhaps larger?
Some larger outfits air scout the rams and drop you in the right drainage, then you go up and find that ram. Others drop you in good areas, and you keep at it until you find a legal ram (no pre-scouting). So ask how they hunt the sheep. No hunting the day you fly, but some guys like the idea of knowing a legal ram is in the area. Others, like myself, want to find their sheep all by themselves (with the guides help, or course).
My point is ask questions so you know how they hunt, and you won't be surprised. Think about the adventure you want and find an outfit that will give you that.
Figure $25,000-30,000 all in to do Alaska in 4-5 years, and $35,000-40,000 for Canada.
A few others to look at. Jake Jefferson Black River Hunting Camps. Alaska Perimeter Guides. Ultima Thule. Kelly Vrem. Riley Pitts Big Game Alaska Guides. Henry Tiffany Alaska Perimeter. Tyrell's Trails. These are ones that I looked into, and believe are good. Please do your due diligence, I have only hunted with Jake.
Be OK with not shooting anything. Be OK with spending 8 of 10 days in a tent reading a book. Regardless of who you go with, it could be unsuccessful.
I successfully hunted sheep with Jake Jefferson in 2017 and am hunting with him again this fall for moose/bear.
