About $5-$20 per shell. Disney usually dumps a few million per night on fireworks since their shells are bigger. When I used to setup city fireworks shows I'd setup $20-$30k. I would check out a van from Pyro Speculators take it to the site, setup, launch and then clean up and return the van. I usually made a $1000 for the day's work that I would split with some helpers. It was a lot of work setting up and testing. I once setup a brage in Reflection Lake at Knotts. This was before Silver Bullet. I ended up falling in the lake that day. I'm too old to set that stuff up anymore.
