If you have the equipment and are legally permitted to fly the mission, then, by all means, do it yourself. It's fun and rewarding! Just be aware of the local regulations and fly responsibly.
However, currently in the UK, you need clearance from the Civil Aviation Authority and insurance if you fly a drone for commercial gain. If you don't want to pay for all the CAA requirements, then book me instead! I have insurance and all the necessary training and certificates. Simple as that!
