I love to ski and it would be great to ski with a provider, but wow are they expensive!
You pay for travel, lift pass, skis, lodging, food, and then about $1000 per day on top.
As expensive as ski trips are, I would think you could find a provider that wants to ski and pay all expenses and not have to pay for their time - the trip and the skiing would be plenty of compensation.
My problem would be finding a provider that wants to ski black diamond runs, bowls, and trees. That's where the women from that website would have an advantage - some of them sound like they are great skiers.
