Just found this video, HD camera mounted to a blimp and it gives you
some examples of metres per pixel at various heights, up to 318m.
It doesn't appear that they are using a fish eye lense, so at a guess
you might be able to get a similar scope from 150m as you do from
300m.

One thing to consider is that the photography won't actually need to cover
the *entire* state. Given the way most rural towns work, it would just need
the point-to-point connections to cover the important roads between towns as
well as the towns
$150 gives you a feed from space... ;)

Weather doesn't need the same accuracy, plus they would orbit slower.
