The website functions as a business card if you will when dealing with other big companies. So it is important that the new design radiates professionalism. (just to be clear, it SHOULD NOT LOOK like a business card, it IS a website).
Below are some designs that I like. When I say that, I mean purely the look and feel of those websites. I don't mean the layouts specifically because they are companies with a different business model. Have a look...
