I doubt there's a significant volume of jobs being generated through Droners that are done outside of Droners. What I mean is, maybe percentage wise, a high percentage is done outside of Droners that came through Droners but the actual number of jobs in total is very low compared to the number of pilots signed up. There can be as many as 300+ pilots on Droners for the larger metro areas. For that big of an area, with populations like 2-4 million you'd expect a hundred or more job posts to come through Droners a week. It's a trickle. So you have 300+ pilots clamoring to get a small number of jobs. So you end up with dozens of pilots bidding ridiculously low prices - obviously, this ain't their day job. LOL.
There's been a lot of hype about the industry exploding since the FAA 107 announcement without any real "explosion" of work. Is it increasing, of course, but a lot slower than most drone enthusiasts had hoped. Droners is the poster child for the over supply of pilots and lack of demand for services.
