It turns out I am the kind of nerd who realizes "my business will soon need to learn how the freight and logistics industry works so we can figure out how to switch to sending pallets to conventions" and gets excited at the opportunity to figure this out.
Right now we bring our booth setup in suitcases and packages sent via UPS. It's janky and boxes break and sometimes pieces go missing.
The ideal: load up and wrap a pallet at home, rent a van to take it to a freight terminal, have an LTL truck shipper bring it to a freight terminal in the destination, rent another van to move it to the convention center, and drop it at the table. Do it all in reverse to get it home.
We are very close to the scale needed to do this.
