psd -> aspx implementation

I have a design (psd) as shown in the attached file. I need the design implemented in a aspx file - also attached as jpg - I will give you access to the Visual Studio project through unfuddle. What I need from you is a css stylesheet and the nessesary changes in the aspx file to implement the design on the page. Please note, that it also should be possible to collapse/expand the packages (you can see it in the psd file).
