This is what the future holds, one agency, one drone at a time. As there are more success stories of drones being used, more and more agencies will add the capability to their toolbox of equipment.
One local emergency manager who has a personal drone provided a demonstration for his parent fire department the day following a big building fire for surveying the damages and doing an initial post-fire size-up. They were impressed with the images that could be obtained from the air.
I have several suggestions for you. One is that purchasing a more capable drone might be a good option. Spending upward of $5K is not too much to spend, but before you put a drone or UAV that costs that much into the hands of a novice, it would be better to have a "training drone" that is more of a hobbyist style of drone.
One of the most popular drone makers is DJI. Their higher-end drone is Spreading Wings S900. And their higher-end Phantom 4 is more for the accomplished hobbyist.
