It is not the expensive camera, it is whether I understand what you want to express.
Most providers mainly sell their equipment: RED cameras, drones, multi camera crews. For major label productions that makes sense. For indie projects it is often overkill that buries the actual story. What matters: does the video capture the mood of your song, do you come across as genuine. That is exactly how I work: smartphone camera, my own mobile lighting, edited by the same person who worked out the concept with you.
Six typical setups are possible, bundled into three package sizes. What this production deliberately is not: an imitation of Hollywood with a crew and drones, for that I am happy to put you in touch with specialised video production houses.
