Three other pieces of advice I can
give:
(1) Like Hayden said, make sure you have enough
people before you start making promises. [In other
words, if you can only count on 10 people to show up,
don't set the field cap at 48 teams.]
(2) It
can't hurt to ask nearby teams (college teams, that
is!) for help.
(3) Don't be afraid to ask for
help if/when you need it. I can think of at least two
"tournament disasters" that were caused when a TD either
refused to ask for help when it was needed, refused help
when it was offered, or both.
