Simple iPhone/iPad Trivia Game

Looking for a programmer/development group who can help us with a very simple iPhone/iPad trivia game. Basic design: Either a question would be asked, or a photo displayed, along with four multiple choice answers. The player would have a time limit that counts down, with the highest amount of points being awarded the sooner they can correctly answer the question. 20 questions are answered. Final score given to the player at the end of the round. Simple! We would supply the questions, photos, front end screens, audio. We need the programming team to supply the game coding, temp screens and layout, some temp art to prove functionality. Game would need to support in-app advertizements, in-app purchases, and future updates. Development time is 2 months. The game is very, very simple! Please respond with examples of other iPhone/mobile apps you have developed.
