I have never held a DA contest before and need some help.

I am Looking for fakemon. I was thinking of holding a contest to help fill the Drawnimals Dex.

I am thinking top prize would be a premium membership to DA (How long would be a good prize?).
And everyone who participates would receive their fakemon in game.

What do you all think? Would anyone help me promote this? Is it a good idea? What prizes should i offer?
