32525 CSS change & Graphical Design

I'm currently in the progress of setting up a new site which is almost completely css based. Since I don't have the knowledge to manipulate my layout accordingly, I'd need some support from someone to take care of this (basically modifying CSS files to my needs). Knowledge of XHTML is a plus. Someone who can create nice graphical style elements (e.g. rounded boxes etc) is preferred. When bidding, please provide your charge per hour since I'd like to get support on a regular basis. Regards Bruno
