331202 simple iphone app required

We are looking for a creative, experienced iphone application developer to build a simple calculator type application that i have setup on an Excel Spreadsheet at the moment. Further to this, a separate page to save multiple results is required and space throughout the application for a web banner/advertisement – the application must be simple, look good & easy to use. Once complete the app will be submitted to the Apple App Store so full knowledge of Apple Store guidelines is a must. If this sounds like something you'd like to get involved with, please provide us with your expected time frame, price quote and examples of your iphone applications that you have created before. We need someone reliable for future updates and more applications. *Please note that you will be required to sign an NDA (Non disclosure agreement) as we require full ownership of all code.
