Tegwin is spot on. We only make money from using our RPAS to do ops for existing clients of our other business.
Every man and his dog are out there touting for work that's not there. Lots of people want pictures but they don't want to pay. There seems to be an impression that a "drone" is only 900 quid so they will just buy one rather than pay to have it done properly.
Buying it is the thin end of the wedge.
