I need a game script writer

We need to create a game in two versions, the first version is a video game for phones and the second version is a real RPG. Like this http://kck.st/2Vk1Q5p , but we do not have the idea or the story around which the game revolves. We need a screenwriter to write a story for a successful game from the ground up. And he will have his share of the profits of the game.
