From what people have said, it doesn't look like you can make a living at it -- at least not more than you could get working at Home Depot. It seems like the best tactic is to find out what non-snowboarding-related but decent-paying jobs are available where you can live and work near the mountain. Preferably flex-hours or shift-work so you can ride weekdays.
At your age, you are in a good position to do this -- no dependants, no commitments built up yet. Ask again, but this time ask what types of jobs might fit these criteria.
In retrospect, "Let's get the goat drunk"
should have been my cue to leave the party.
