Iphone, iPad Game Development

I am looking for an experienced iPhone & iPad developer to code an iOS 4.0 compliant game app. The basis of the app is geo location data of world wide cities. Geo data will be purchased separately if it can not be sourced for free and is not part of the bid. The game needs to be connected to a high score keeping portal. Either such service exists by a third-party or you need to create an external online score keeping way. The graphical interface is 2D with either a globe or flat map of the world that is showing country borders. Once zoomed in further rivers and lakes are visible but not cities or other features. The borders extend down to a state level. Otherwise the graphic is text, scores no moving parts other than scrolling and pinching of the map. Players can select from different play options and geographic regions. They can opt for timed or no timed games. They can select different difficulty levels. Part of the job is to create a free version with a limited city set and a paid version with the full city set. The full design specs will be available after a non-compete and non-disclosure document is signed. The job spans the whole creation and testing process. I will provide detailed design and feature specs and work closely with you during the work and testing phase. I am not interested in low quality work. I expect good efficient code and good design. Work is to be done to a realistic time frame on time.
