iPhone game

Hello all. I am looking for an iPhone developer (coding and design) with many years experience. The basic idea of the game is to drive a vehicle in different settings and destroy buildings and other obstacles in a 2d setting. The game need to have a single player mode, where players can play different levels. The levels needs to be completed within a certain amount of time. More important the game needs to have a multiplayer mode, where players can play against each other. Besides players can upgrade their vehicle with in-app purchases. I will send the complete business plan after more intensive contact and a non-disclosure agreement. Please contact me if you think you can make this app and you are interested. Requirements: 2D Gameplay (like clash of clans) Driving by combination of touch and gyroscope Single player mode Multiplayer mode In-app store options Integration of advertisements Simple design however skilled (like bike race) Years of experience with game developing Estimated costs Willing to invest in a long term relationships (updates etc.)
