CSS mockup- two CSS documents: Need cleaned up code

I have a project I am working on, it's a website with a template I got from template monster that has been a mess from the start. I'm looking for someone who can make the CSS look good and be clean code/ validatable. You can see the project files to see the layout. This is a really simple job for someone good with CSS, my skills aren't strong in this area and I need this fixed ASAP to get the project done. I will provide the CSS I do have and screenshots. Need this done in 1-2 days.. at most.
