That's harsh Ozzie,
I would cover the floor with a barrier, put down plywood and set it up in my living room if I didn't have a shop!
To the OP,
My Hermes dealer will cnc me special plates out of brass if I want to cut logos or something special for real reasonable prices. All I do is send him the line art and he scans it and he uses one of there cnc printes to cut it for us. We gave up on Electro chemical etch as it sometimes would not deep cut evenly. It would have an occasional deep pock mark right in the lettering. I love our motorized New Hermes Engraver. It wasn't cheap at $3000 new but the support and quality is first class.
