Car Quiz for iPhone

I would like to create and iPhone app similar to city quiz but with cars. In this game, the objective is to guess the car model. To achieve this, users will dispose 3 - 4 pictures of the car and letters in which the correct letters will be mixed in with wrong letters to confuse and increment difficulty. I will attach some pictures so there can be some examples of what exactly I would like to do. The application development is fairly simple. I will provide all the data for the application such as Pictures, Car Names, and any other information you might need. I would also like to integrate Facebook to be able to share, ask friends and also have the option to purchase coins for which would be used to show a hint, a 4th picture, a letter etc. Thank you, Please if you have any questions don't hesitate to ask.
