I had my front bumper done by Paul's Plating in PA 2 years ago and I'm very happy with it. They fixed one hole that was overtightened and sucked in and straightened one spot out right at the crown of the bumper where it looks like someone ran into something. The original quote was $950 and I actually hadn't noticed the crown damage until I took the bumper off. The damage was pretty significant. I let them know before shipping it and they fixed it and still charged me the original quoted amount.

FYI- the rear bumper on my car was purchased from Bumper Boyz about 15 years ago and it still looks very nice. I don't know if you'd get the same product today though.
