We addressed this same question on the Drone Deploy webinar recently but didn't get a response then.
We're more concerned with lost Revenue then we really are as much about safety, with a few exceptions. We're realistic and truly believe what the FAA has done with sUAS and how they did it was all wrong and largely ineffective.
That aside, we've put a page on our website that addresses and educates prospective clients and other visitors on how to hire a drone operator.

We've confronted 2 illegal operations directly and been approached twice regarding illegal commercial night ops that turned out to be someone else showing another way illegal operators affect our business. As a result we have had to become actively involved in our community in educating everyone has a whole on the do's and don'ts regarding commercial drone operation and safe drone operation in general. We consider it the added cost of helping build a new industry and only hope that someday it pays off in the future.
