Create CSS Sprites / Update Magento Template CSS

I need an experienced Magento template programmer / website designer to create CSS Sprites for the images on my homepage and for template images. You must reduce the number of images and http requests to as few images as possible by using CSS sprites. Use the tool at: [login to view URL] to find out which images you will need to create CSS sprites for and to reduce the number of http requests for those images. Create the image sprites and update the CSS for the templates. There is one main template but there are 4 color schemes for the same template. You must update the CSS and images for all four templates. Please provide samples of your work using CSS sprites with Magento templates.
