Design company pocket folder, letterhead, business card

I need to design 9 x 12 presentation folder, Letterhead, Envelope and Business Card design for our software consulting company. I will provide the logo and some content and you will provide all other design elements/graphics. You MUST show me examples of your presentation folder design work or you will not be considered. I would like to see these examples online. The template must be delivered in .PSD or other editable, layered format so that we may alter it in the future if need be. If you are able to create a quick mock-up demonstrating your ideas this will greatly increase your chances of us selecting you as the winning bidder.
