Design an App Mockup

I'm looking for a storyboard UI design produced in Sketch ([login to view URL]) that outlines a few screens of a conceptual iOS app. The app will serve up a 'word for the day' in a regional dialect (English - e.g. Geordie). The technical aspects are done and understood, but I need help with creative branding/look and feel. The storyboard design should include a number of screens - e.g. 4/5 - enough to convey the basic app functionality and arrive at a branding/look and feel that we can carry forward into an implementation. This should include an app icon. I've specified Sketch format rather than PSD so we can export any required assets directly in the relevant resolutions and import into the build process. I can outline the basic functionality of the app, and provide some simple Sketch storyboards I've started to help outline the functionality. I'm looking for someone to take this as a guide and produce an innovative UI design and branding that will bring the idea to life. * The app will fetch a 'word of the day' via the web * The user will be able to swipe through recent days * The user will be able to share socially - ideally, given the lingual nature of the app, Twitter should be a heavy social focus * Ideally the app will be a platform that can be tailored for specific regions - we'll go with one to start with, and I'm keen to use regional images within the content if possible. The aim is that these storyboards/assets would be used to produce and refine a working prototype of the app. I can provide any further information as required - just drop me a line.
