I belong to a company that produces photo books and all types of photo gifts. We are developing an app for iOS and Android in order to make possible to our clients to buy our products through their smartphones.
We already have Android/iOS developers for the back-end and most of the app's mechanics but we need someone who can do the interface design and execution, (program or build the XML code for the interface) .
Currently we are fond of shutterfly's app look and feel, so you may use that as a guideline to better understand our needs.
If you have any doubts, feel free to ask.
