I'm in! I'll supply the 10 acres of land and y'all supply the heavy equipment to build the berm, and set up a realistic training range course. Heck, we could probably get a couple of junk cars from the salvage and get a little dilapidated house to bring in for building clearing exercises.
Heavy equipment? We are trying to do this cheap so we can charge for it cheap. Can't we just rent a bobcat and collect some old tires?
