Create a whiteboard Animation drawing video

I need a white board hand drawing color type sketch commercial...for my website and products an example of "color" and art "quality" that I am looking for can be seen here.. [login to view URL] This will need to be complete project illustrations, color, editing I will provide script & voice over. For final edit. I will load full milestone payment for project upfront . I will only release 1st 1/2 of the milestone payment once I see the story board and agree that the art work is acceptable. I will issue final milestone payment once I view and agree final project has met all specifications.
