HTML5 and CSS3 Expert needed ASAP - Sencha Touch a PLUS

We need an expert at HTML5 and CSS3, and preferably who knows the Sencha Framework for RAPID development. These technologies are new but they're not that complex.. The app will be relatively simple, will have 5 tabs/section at the bottom, one will show a video, one will show a calendar, one will show just plain text, one will have a form to fill out, and the app will take username/email and password to subscribe users for updates from the app.. Simple. it's basically a website with the html5 css3 front end UI. PS: The backend database work would be done by us, but if you can do that too, it's a plus for us to chose you. Remember we will want to see SAMPLES of work done.. Don't bid just because you THINK you can write html5, we will ask you to go and watch this video: [login to view URL] Thanks!
