Reference Needed - Boat Carpet

I live in Glasgow -any help for carpet references would be great. I want quality work at a fair price.

I saw an ad on Craigslist for carpet replacement in the Gallatin, TN area. I called the number and the gentleman sounded legit, but he works on the side from home(not an established business entity). I was hoping to find someone who can vouch for him/offer a reference. His name is Lionel Green. I want to know A) if he is trustworthy and B) if he does quality work. Any info would be appreciated.
