Introductory Video for Gaming Platform

I'm looking for an introductory 1min video or "how it works" close to the WeCoupon example: [login to view URL] I'll provide the script and voice for the video like the example above. But I'll need the animation/style and a soundtrack explaining the platform. The target market is Brazil, and in the final video will be in portuguese, but we can produce everything in english and translate in later stage.
