I remember there used to a business which would take lots of pictures of houses and then send someone door to door to try to flog them to the homeowners. I assumed that was long gone with the advent of google earth and so on but maybe it still works if you've got the entire set of parents of try to sell to (with the school taking a cut, perhaps).
In any event, it's still airborne and if, as you say, it's single-crewed, then it will be a very tiring sortie!
