Replying to Snowmakers?

Okay, I live where it doesn't snow, but we got an indoor snowdome down the road, and the park there kinda sucks a lot of the time, so me and the rest of the people I ski with are bored. It costs $250 to get a trailer and car full of snow from the snowdome (that's what they charge) to set up an urb. Of course, $250 can add up, and is there andy kind of snowmaking machine that like 8 of us could pitch in to buy so that we could hit urbz all the time? Any advice would be appreciated.
