I've got a Google sheet I use for all my tournaments, where I have the list of events, a hyperlink to the flier, and another one to the tournament in TrackWrestling. That way rather than sending out the same flier hundreds of times, I can just post the link and send it...if I update the info on it, the doc updates in real time and they can always click the link to get the latest info.
The same idea could be put into place for teams looking for matches, or looking to get into (or get teams into their) tournaments. The main issue with that is getting the word out about it and making sure it stays up to date.
