Android/iPhone Prototype required for Order Placement App

I need a prototype application developed for Android/Iphone platforms. Its a basic app and should not be too much of a work for a pro. The app is required to allow the user to browse/search through a shop catalog, browse through items and then go through an order placement form to place the order. After placement an order tracking number is generated for reference. This order should also be available for view by the shop owner, so possibly a web-service is required to post the order detail to a database hosted on the server. A simple/dashboard page will be required for the shop owner to view the list of orders and hide completed orders as they are processed. I need it to be developed quickly and the app design should be professional and elegant. I need to know the implementation strategy(technology/languages used for the implementation) and how long will it take for it to be developed and for me to test on my android/iphone.
