Not obvious stuff from our little comp that is now a 400 entry medium sized comp.
If you competition grows, you need someone to get the word out - print fliers and electronic means. You also might need drop offs at remote locations like the LHBSs in your area, so that means pick up from those locations and transport to the judging site - this can take most of a day. Sorting is a job that can use extra help.
My wife appointed herself the title of "Queen of Swag" this year. Her job was to contact suppliers and get items to be distributed for judge and steward gifts, some cool stuff that also went to the BOS winners in beer and cider/mead, and grab bags at the end for everyone. Lots of time to contact, sort and store the items, and send thank you notes to all that contributed.
