Simple website design (2 pages)

Hello, We are developing a simple web application which acts like a file browser on the server. We have a very simple interface right now (screenshot attached). We would like to make the interface look far more professional, and need some help with this. Your job would be to design two screens - a simple login screen (which doesn't currently exist), and a second screen which would be a redesign of the screenshot that is attached. We like the design philosophy behind FlatUI ([login to view URL]). Other details - - The file browser uses a few JQuery elements (autocomplete and calendar). - The design must be in simple and lightweight CSS / HTML. - We need this done soon (< 1 week). Any other details can be discussed over email or IM.
