Wanted <> trustworthy Electrical shop in WNY

Anyone in the Western NY (Buffalo) area knows of an electrical shop to replace harnesses for a '69 Coronet, that had a fire. A lot of places around, but wondering if anyone has a good experience with one. I know it's a long shot, but what the hell. I have checked yelp, and have seen good recommendations, but wonder about working on a 50 year old car. Before you say it's not that difficult, I'm an old boomer, and if it were 15 years ago, I would do it, but those days are gone.. thanks for any info.
