Ski Trip in the United States

I am planning on taking a ski trip for about 3 weeks starting in the middle of December. I need information regarding price, dates, hotel rooms, deals, and more. First, I will provide the following facts: I live in Cleveland, Ohio. I will be driving my own vehicle during these 3 weeks. I want to drive West. The vehicle I drive consumes on average 20 miles per gallon I want to keep my ski trip under 2,000 U.S. dollars (plus or minus 500) for gas, food, rent, and ski passes. I have all of my own equipment. I want to ski in at least 3 different major ski resorts, i.e. mountains ranging from 5,000-15,000+ feet in elevation.
