Which currently requires a pilot's license.
It is estimated that the commercial certification is at least a 5K expense for a business or individual.
Then there are the privacy rules...
For instance one idiot decided that it would be neat to film our town's annual event.
So he took a bunch of videos and posted them all over the web stating that he had been "hired" to do so by the town leaders.
He did this in violation of the FAA SFRA, FAA privacy restrictions ( e.g. no flying over private land, no flying over crowds, etc. etc. etc. ).
And then he went as far as hanging out a shingle and advertising his services. Needless to say he is in a bit of hot water over all of this now.
