This isn't the section for contests, this is the section for stories, so you can't run this here, sorry. If you want to host this contest then try posting your idea (a summary of what your contest is about) in the
contest idea thread for feedback. In
this thread there is a list of people who have expressed an interest in being judges, though you're certainly not restricted to those people alone. Finally, for information on posting and running contests, read
here.
