Explainer Animated video with voiceover required

We require an explainer video to use on our Royalty Free Music site.
The video needs to be around 1 minute long and be animated in a cool and funky way.
We can provide script etc but will need a professional sounding voice over to be recorded as part of the video.

Something like the video on this page will give you an idea of what we want.
