I occassionally do some aerial photography work in the area and love it, but
there's not enough of that kind of work down here in South Texas.

I wouldn't be too sure about that...

If you have construction projects of, say, a million $$ or more (apartment
complexes in particular, or governmental buildings, etc.), or have fair
commercial real estate (excluding residential) activity, you may be able to
generate "new" aerial photography business as I did.
