Flying the drone is a major issue when deciding whether to buy or rent the drone. If you decide to buy the drone then you will have to learn about how to fly it too or it will not serve its purpose. However, renting the drone would spare you from having to learn anything about drone flying.
The companies who rent these aerial vehicles will provide a pilot for you that will take over the flying duties. You would just have to tell the pilot what to do and he would deal with the rest. Drones are aerial vehicles and thus require proper licensing before they can be used or flown in the air.
