Team of 1. I have assistance with art, and people helping day of, but the 99% of the planning, money up front, etc. is me.
Just a stupid Excel sheet I made. I should just use some generic software out there to make it easier.
I use a mic and announce rounds. I could print and hang sheets like FFG, but the venue is too small for that, and a projector wouldn't work in the space. Pairings in the teams is handled at the table by the teams themselves. I have someone from each team come up each round to verify the results. I then pair by teams, and have each player keep their individuals score sheets to determine seating.
Not many other things to know. Planning as much as possible will make your day of easier. I have all the teams sign up ahead of time so I can have my spreadsheet set, and first round pairings ready ahead of time.
