App prototype for Android Tablet - Appcelerator Alloy

I need a proof of concept/prototype done to demo to a client. Target platform is Barnes & Noble 7" Nook Color. This may lead to full app development if the client likes the prototype. A clickable mockup of the app is attached. The main part is the video player, which should behave like the way Youtube does it here: [login to view URL] Important: the video player needs to work offline, so the videos need to be stored locally. I can supply videos for testing purposes. This is a prototype so the interface can be rough at this point. The important part is to show how local videos can be played. Also important: I'd like this prototype done in Appcelerator using the Alloy framework.
