Do you know any sites that make professional videos about a website/product?

Hello, I want a youtube video for my game site,just explaining the rules of my website and how people can earn points and stuff.


I have seen some sites that have videos, made with stick figures and clipart. But i want a site that can make professional videos. So I can promote my website on Youtube.

Do you know any websites that make videos?

here is an example: http://wistia.com/blog/how-animated-videos-can-make-your-product-shine

I want a video like that promoting my website.

Thanks
