My two cents on this, is NOT to bargain shop sheep hunts. To provide a guided sheep hunt is an expensive proposition, and the guys that are good charge what they need too to make a profit and that can be well over $10,000. In remote, expensive to hunt areas, guides like R&R Hunting are charging $18,000 this year.
Guides that the offering hunts on the lower end of the price scale might be doing it because the have a good, low overhead, spot to hunt, but most are either cutting corners on the service or are running an excessive number of hunters in their area to try and turn a turn profit. I'm met my share of disgruntled sheep clients in the field, so buyer beware and check references extensively. There are plenty of top notch guys out there, so no need to settle on second rate.
"All in" costs for any guided sheep hunt are going to typically run WELL over $10k, once you add flights, lodging, NR tags etc. Many locations will require a flight to a village and/or a charter to the base camp that is not included in the guide fee but can often be quite expensive.
