Hi, I'm pricing a custom staircase containing treads with punched metal inset into wooden "trays". Not sure of the spec of the metal, but I am thinking steel 1/8" thick with a custom pattern punched into it. Any idea about how much this sort of thing costs? I've looked at various metalworking websites, but I cannot get a ballpark idea of price from them .

Here is a link that might be useful: punched metal tread
