You could do it with the help of the PGA of America. They would keep things on the hush, but would have the infrastructure in place. You would select a small number of golfers with charisma and ties to the area. You would pick an exciting format (match play 6s comes to mind) and you would involve the crowd (if your player wins a match, you win something, too.) The point would not be about $$$$$, but about giving forward.
When Jim Thorpe lead the 1981 US Open at Merion and ultimately finished t11, he did a goodwill tour of courses in the Buffalo area that summer. I followed him at Audubon golf course in Amherst, and he was great. He shot 73, 2 over par, could not get a ball to stop on those concrete greens, and could not make a putt. I saved his divot and ball for months, and if I wasn't already hooked, he did the trick. He would simply show up and play. Unbelievable memory.
