Style Sheet Changes

I have 41 sites that are running of the same css and all look like so: [login to view URL] I want all 41 of them to look different in layout but still look respectable and of decent design... I will provide the actual url for as many are your can do when we agree. Please bid the about per stylesheet so that i can keep track. I am happy to break this up into 41 different projects by different designers in order to ensure uniqueness, 1 big project for one person, or somewhere in beteween, so let me know how many times (max=40) your would like to update this css - ensureing that it LOOKS completely unique every time.
