If you visit www.barefootstudio.biz the owner, Kent Skewes will hook your clients up with whatever your hoping to inscribe on their plaque. You can get it in marble, and slate and he can add images as well. You can totally modify them to whatever you want. He will also inscribe your contact information and logo if applicable. If they break, he will redo them for you and he has such a fast turn around! All of my clients get one and they are so impressed with them! So cool!
