Create a Demo iphone App (not fully functioning)

Hello, I'd like to have an iphone app created that I can use to show to prospective customers to understand the demand for the idea before I have the full working app created. The demo app is quite simple and the main requirement is to design each screen page with a small amount of functionality (take photos) and I'll need to be able to upload different display information to show to different prospective clients. I'd like the work completed in 10 working days. I've attached ideas for screen shots, a more detailed brief and examples of the different display information I'll need to upload to the app. Thanks, David
