I need a game designer

I have a niche adult fetish website and would like my users to play a game based on the content I sell. Using some of the models on the website look a like. The user is to pick the type of character he wants to be (Having a choice of a few) then goes and looks for the models, he walks up to a model while they stand all sexy in sexy skimpy clothing and punches them in the mid-section. The reaction of the model can be doubling over to going down on her knees. The model recovers and gets up to be punched again. I would like to start with only a few models then add models as the game becomes more popular. The scenery can be in a castle dungeon type setting. I would like the models to be realistic looking, the only sounds would be the blows from impacts and the Ouufs and Uhh sounds from being punched in the stomach.
