Matt,
I certainly wish I lived a lot closer to your airfield - good luck with your venture.
Find out the where your local Motor Clubs meet and make yourself known to them. When I was involved as a competitor in rallying we were desperate for meeting venues and often had to make do with pubs that didn't really want our business. You may find it opens doors into a possibly new range of contacts too - many of the folk I rallied with were keen on aviation too.
Best Wishes
PD
