Id suggest you get these, already raw, and if you have the money to blow, go for chrome plating. There was no one local and I never pursued getting prices.
The great thing about the above item, is with elbow grease (lots), sandpaper (lots), and a healthy dose of mothers mag, they come out like this. I havent done any work to the inside yet, wanted to show what the raw looked like vs polished. I still want to go down another grain in sandpaper, cant polish out a few scratches, maybe 1000 grit.
Note the reflection of my hand in the last shot, I blurred it a little moving in the shot, but you get the idea.
