The ONLY soccer that will succeed in this country is your plan, built on the English and International models. I wish Beckham could understand this and join you instead of his pipedream in Miami.
Community involvement is clearly the way to go. Now, when households can afford less and less; outrageous ticket prices at all major league venues in every sport coupled with insane cable TV prices, if you can weather the storm for ten years you will be hailed as a true visionary.
Good luck in this venture.
