I found a shop in NE Ohio that does chrome plating: Custom Chrome Plating. I inquired the cost to chrome door scuff plates which includes taking out all the dents: $400-$600 a pair.
Dean I am with Ray on this quote,way too much
Given it is only a pair of door sills,I would expect to pay someone between $80-100 each tops for the process. You would drop them off and pick them up of course but more than adequate for the time and process.
