I can make it out of whatever you want, within reason. Stainless steel, brass, copper, no problem.
I'd prefer to not have to send it to a plating shop but me what you want and I'll suggest how much it'll cost. I doubt it'll be more than £200 for a set, though, unless the thickness gets to 6 mm or more. The drawing MisterDiodes linked to suggests 2 mm thickness. I don't actually know anything about the ESI SR1010 so 6 mm might be way too thick, I have no idea.
