For Executive Golf - Email Richard Baier as he is the head of all things of the District and is a good man who will direct you to the correct person and will follow through

For Championship Golf - start asking at one of the developer owned championship golf shops.
As far as I know, there is no one person in charge of both although the developer does own the Championship and has a lot of influence on everything in the Villages. Good luck trying to contact them.
