If I wanted to slowly start supplementing my firework shows with some drone light shows, what would be the best way to go about doing that? I would be a complete novice, so looking for something that is easy to program. This would just be for my personal use for 4th of July, not trying to do anything professional or anything like that. Are there any DIY kits out there? Resources I should look into? Can you rent preloaded shows where they just send you the case of drones that are pre-programmed and you just set them up and turn them on and start the program?

Drone Blocks, Dojo for Drones, and Fylo sell consumer light show kits. A 10 drone DIY light show would cost you about $6.5k - $10k.

UVify and Firefly can offer turn key solutions at ~$1.5k per drone give or take when purchased in quantities.
