As far as your local team league. I think you made it too complicated. And again trying to get every course involved from the beginning is probably too ambitious. Shoot for four - 4 man teams for the first league and grow from there. Keep it simple, raw score total wins the match up.
Kind of like the Tavistock Cup. Started out a few years back as just Lake Nona vs. Isleworth. I think this year they had 7 clubs participate. Though, I think it still only alternates between those two courses.
