PSD to DNN CSS

I require a DNN CSS style to be created from a design in photoshop. The design includes a border, banner, menu, container and is fairly simple. This style sheet should be designed with the ability to be applied to any DNN created page. The page width 800px fixed width and height adjustable. The container and menu must be able to use standard DNN functionality to add and edit content. I need this to be done within about a week and only have a budget of $AU300
