If you are organising a chess tournament try SWIPS software.
HOW TO ORGANIZE A CHESS TOURNAMENT AT THE REGIONAL LEVEL

There is also the cost of Swiss system pairing software. Also some TD's bring a portable printer and laptop.

It's a pretty good list. I am the organizer and TD so no commitee for my tournaments. Other than that I can't think of anything you missed at the moment.

In the U.S. some fees to consider are the ad in the Chess Life Magazine and any other promotional costs. After the tournament is over there is a fee for rating all the players.

I use swips - www.swips.eu
