I would definitely contact some of your local delegates and they will be able to answer all your questions. The delegates usually have all the timers, stopwatches, etc. The money from the entry fee is used to pay for all the expenses.
Since you have been to so many competitions you know how they are run so that isn't an issue.
I don't want to sound like I'm advertising but I just did an episode on this in the cubing podcast I host.
Episode #14.
Hope this helped.
