Develope cross-platform app for a Fashion Week event on iPhone/iPad and Android -- 2

I need a cross-platform app designed for Apple iPod/iPad and Android smartphones. The app should serve as a main source of information after the website for a fashion week event (working online and offline), Screens or categories includes information about the event, shows and talks schedule, contacts and map section. I made some sketches that could serve as an initial wireframe for the Fashion Week App, I need it to be professionaly designed and built into a flat user interface app for iphone/ipad and android.
