Saw RGJ post an article about a women's touring group. Looking it up, they do an 8-day dirt ride through Colorado, listing some of the specifics. $2,999 to attend and that doesn't include having SL cooking a gourmet breakfast for you every morning.
I'll link it, just for ideas. Their route may have potential.

Good thing you're (GM) providing a cabin for this upcoming Mammoth trip. Otherwise I would have to charge you a couple thousand for the privilege of riding with me. :evil1
That's a lot of $$ to do a route that is well documented which you can just purchase a map from BDR, get free gps tracks and easily figure it out on your own. To each their own, I'll stick to planning my own trips for now and they come in well under $375 per day, ouch that's a lot! :2cents
