Metallic buttons and icons

I need a set of 7 x metallic buttons and 4 x metallic icons in .gif format Each button and icon will have a picture on it with a metallic background. The pictures are basic symbols. All need to have 3 versions - Enabled, pressed and disabled. So a total of (7 + 4) x 3 images = 33 images Size of each to be 500 x 500. 3D look and feel, so when the user clicks on the button it appears to be pressed.
