Zen Cart Expert

Seeking someone who has extensive experience with Zen Cart and CSS style sheets. I operate a website with 100's of products and each product has its own unique style controlled by an xml file. The xml file dynamically loads the page attributes such as background color, tile images and form variables. I would like to the ability to define the font colors and background color of the data which is generated by zencart such as font colors and background colors. Each product has its own unique xml file. I would also like to create some new categories on my site which will require some db query to create the new parent > children relationships -
