I don't do this but thought about it.If you pretty much know your going to the same customers each week.How would a metal calendar bd. work? Have the names put on magnets so you could move them around at ease.Then have some blanks made with some sort of dry erase material for the surprises that pop up.Just write on those until they become permanent.Probably work best for the maint end of it.
