I think that sounds good, if this contest works out, than we could have one for those who like to write poetry, or smallest, biggest. , but starting out simple is the way to go for the first contest to see how it works out. I think you should be in charge of it since it was your idea, make out the ground rules, when to start, when it ends, who can enter etc. etc.
I am willing to donate a prize or some money for the contest.
