Often times, a small crew of 2 or 3 can manage an entire shoot. Other times, you may need additional crew to operate special equipment or direct multiple shooters. Also, consider whether you want additional talent like makeup and hair stylists, actors, interviewers, voiceover talent, etc.
Drones require specially licensed operators. Interviews typically require seasoned journalists. Heavy equipment simply need more people (grips) to help haul, set up, and tear down. Audio technicians manage multiple audio sources, etc.
Although those are some of the main considerations in pricing a video shoot, the next consideration is post production.
