Congratulations on drawing a tag! Any reason for wanting to hire a guide for a ewe tag? I had a ewe tag a few years ago and am applying for them again still. It was an amazing hunt for way less points than a ram tag.
CPW has tons of resources for sheep tag holders. They setup a Q&A session every year, and hold an event with Rocky Mountain Bighorn Society where they will pair you with previous tagholders.
If you call a CPW biologist, they will point you to the areas where sheep reside, so I wouldn't be set on paying a guide unless that's the experience you want.
Use this link, find your unit area, turn on the sheep summer concentration areas layer, and that's a pretty great starting point.
