I know it is not on the same size and scale but I just had a valve cover chromed on my 223 and it was $180. I thought that was high but they had to blast it clean too. Chrome has gotten expensive. I wouldn't doubt it being $1000. I just saw a 1957 grill on Craigslist a month ago in Sacramento. It was chrome. The guy wanted a $150 for it.

Better off sometimes finding one and then selling the old one!
