Here is some advice that you did not ask for. Do not use that stone in a wet area. If your heart is set on this stone, please check to see it you have hard water, this stone is know for oxidation when it is use in areas that has hard water. If you do have hard water, make sure you get a member of the NSRA or a very good restoration guy that knows how to seal this stone correctly.
Now for your install question, we have a few installers on the site, but your best bet is
John Bridge Ceramic Tile Forums - powered by vBulletin they always have installers online.
