Developer for iPhone Scan-application

I’m looking for a developer who can create an iPhone application to be used together with our mobile website. The application consists of two main search functions. One by scanning a barcode (with the build in phone camera) and one dependant on search query input by the user. Both search functions have connect to the mobile website with the search (barcode/ean or user input) in the query string. Besides the search functions there have to be two other tabs in the application. One with coupon codes and one with popular products. For both tabs the information will be provided in a xml file available on the internet. Information in the xml file consists of an image with text information and has to be displayed in the app. Design for the app is ready and available on request. Design for the icon, based on our logo, has to be made. App has to work on iPhone 3(GS) and higher. The app needs to be published in Apple App Store. Any help with this procedure would be appreciated. It’s important that we receive the source code from the application and that the worker is available in the future to make some modification on request. Same application is available as Android app as a reference.
