Chris, Clear Creek is fun, but it's not the most beautiful stretch. It's lovingly known as "the ditch" by more than a few guides...
The Arkansas has lots of opportunities for work. In my experience, AVA is a great company to work for and they run Gore if you're at that level. Timberline and Nova are also both known for having pretty solid work for their guides.
If you're interested on the Poudre, there are not many video boaters or safety kayakers on that river. The spots there are are probably taken. However, it's a blast to guide! There are only 5 companies, and despite all the trash talk, all 5 seem pretty solid. Ask what sections they run though, as not everyone runs the class 4 stuff.
Hope this helps.
