Where to advertise a flying club?

All,

We are trying to increase membership in our Phoenix-area flying club
and was wondering if anyone had ideas of where we should advetise?
(already tried flyers at the airport) Does anyone know where I can
purchase a mailing list of all pilots with a current medical in a
certain geographic area? Maybe sending postcards would get us
somewhere.

If anyone's interested, we are based at Chandler and Deer Valley - 2
Archers, 1 Commanche, and we will soon replace our Arrow with a 1998 or
newer 182. All planes have GNS 430s. All members are equity owners -
basically a large non-profit partnership, 54 slots. We've actually had
declining membership because many members are buying their own
aircraft.
