Since you are an experienced sheep hunter you already have a good idea of what you are getting into. The first thing I would do is determine what kind of sheep I am after. Will any legal one do or do you want to hunt an area that may hold a truly huge sheep. There are plenty of operations out there for under 10K that offer both types of hunts. The Brooks, for example, is expensive not because of the size of the sheep, but because of the remoteness of the area. This remoteness means less competition which adds to the quality of the experience. Other areas may hold huge sheep and be hard to hunt because of the terrain, competition, or difficulty in obtaining a drawing tag versus the over the counter tags.
There are several books and videos out that deal specifically with some of the details in hunting dall sheep. Sheep Hunting in Alaska, Sheep Stalking, Quest for Dall Rams, & Sheep Hunting the Alaska Range are all in my personal library and offer some good insight into how to prepare and what to expect. Of course there are others. All are good.
For me the draw to sheep hunting is the country that they live in. It's like stepping back in time to hunt like it was 100 years ago. No fences, no bridges, and scary cliffs! Nothing like introducing your son to sheep fever and ruining his sleep for years to come.
Good Luck,

PS Remeber to hunt with your kids, not for them.
