If it were up to me I'd consider winch launching seeing as those mountains are very conveniently located.

Some advantages of a winch operation:
1. I would think that a second hand winch would be much cheaper to purchase than a type certified, tug aircraft. You don't need the latest SkyLaunch system to get gliders airborne.
2. Operational expenses of a winch are typically a fraction of those of a type certified aircraft. No annual inspections, no mandatory expensive overhaul schedules, much lower fuel consumption per launch, etc. A tug costs money to maintain even if it sits in a hangar doing nothing over winter.
3. You don't require a pilot with a tug rating. Sourcing and retaining tug rated pilots appears to be a problem for a number of soaring operations around the world.

I'm sure Bruno from Utah Soaring Association (Nephi) would be able to point you in the right direction if you are interested in setting up a winch launching operation. https://sites.google.com/site/nephisoaring/about-us
