[Request] Free theme with video hero background

I currently have a page setup for a client in staging at http://pushinwater.x10host.com and I like the way the page is currently setup. It is using a theme that I find very difficult to use, however. The client would like the hero-shot/splash image instead to be a background video that is currently hosted on YouTube (that he owns on his channel). Is there a theme that is easy to implement with this feature? Free is a bonus, but not mandatory if it is exactly what I'm looking for.
