Or just order the theme at wasd?...
Doubt that anyone have made a theme of what you want and then also is willing to sell it, fair price would probably be what wasd takes for theirs anyways soo.
(If you maybe didn't notice, you can remove the actual keyboard from the wasd custom keyboard design which should drop the price, also use only engraved keys or only lasered and not a mix of lasered and engraved..)
