Replying to Jump building help?

So my friends and I have a bag of rock salt, some shovels, our skis and boards, and 12+ inches of snow that fell on Saturday and Sunday.  We want to build a hip that goes off to the side of a tee box on our local golf course so that we land on the banked other face of the tee box.  We only have about an hour and a half of precious daylight, so we need to work fast and be effective.  Any suggestions?

P.S.
We also have some big-ass flashlights.
