RE: Cost for Aerial Photos?
Look at a small local airport for someone,, if not there will probably be a message board there you can put up a note.
I bought one that is 12 years old for the property I hunt,, have had a fair bit of logging done since then and some building, but believe me its worth its weight in gold!
Got lucky in the last couple years Ive gotten to know the person who owns an adjoining property. He likes to buzz the cottage early am in his float plane. Going up this summer and going to take complete aerials with a regular camera, digital, and videotape.
