Guide you to what? If you are going to be there this week.... there isn't much open so you won't need a guide.
I think there are what, 2 runs open? Not much snow expected this week either, so just enjoy a few runs and have fun while in town.
I am also doing Beaver Creek, I think you are exaggerating about 2 runs being open(By the time I get there, they just opened so for now 2 runs open.). Whatever this trip only cost me around 300-400.
