Hi,
I have a lot of experiencing developing custom themes, and slicing, chopping and optimizing the graphics templates for integration. I am also quite adept at custom module development, templating and the Drupal API.
Not all of a graphics template gets sliced into the theme, normally you will require the photoshop graphics to be integrated sensibly(banners, backgrounds yes), with buttons, plain panels etc. reproduced by CSS/CSS framework in line with modern standards for optimal performance. Just sayin.
