Home page redesign for B2B web site

We have developed a new web site. But we are struggling with the design of the home page. This is a b2b web site. I'm interested in finding someone who is very knowlegeable about web page design who can provide a sketch or even a layout in a quark/indesign/publisher/page plus or pdf format.
I will provide a link to our prototype web site and a full briefing of what we want the home page to do.
