Wordpress Website Makeover Help - Better Graphics/Appearance

I need someone with deep knowledge of Wordpress, CSS, JQuery, Graphic Design and some PHP to help me with my site makeover. What I want done is a facelift - better look/appearance of the site as a whole. This is NOT so much about programming. It is about making my site look better. Everything is done using Wordpress for now. I just want someone that will make the site look professional. I am a programmer myself. But I need someone to help me with better look and feel of the site. This is more of graphics, CSS, or web design work. A deep knowledge of how Wordpress is important. Please respond ONLY if you know Wordpress, CSS, graphics etc. Php is required also but not much.
