Just for pointers you could take at look at
www.aopa.org and
www.climbto350.com I continuously see ads for CFIs there, even though it`s not on a day-to-day regularity. AOPA also has a directory of ALL registered flight scholls in the US, so you might want to get your hands on that too, especially since it includes phone and fax #s.
ACA are also hiring...
