MCommerce application for iPhone

Hi All, We would like to build mobile commerce application through which we can sell the ebooks. All the functionality applicable to an e commerce application needs to be built as part of this mcommerce application and the targeted platform is iPhone. Experienced iPhone developers who already build similar ecommerce app for iPhone only need to apply as this needs to be completed in a week time. Payment Terms: - 50% of the payment will be made once the app is submitted to iTunes - Remaining 50% of the payment will be made once itune approves the application. You can use your own developer ID to submit the app in itune.\ Thanks
