My previous tire swap was handled by Criswell Chevrolet in G'burg who are a big Corvette dealer. Perfectly satisfactory, but it was some years back. Last swap was wheels and tires, so did not need a local shop.
Go on the Tire Rack website at the top of the page and look for approved installer. I took my rims to Quality Discount Tires in Kensington, MD. They did a great job mounting them. I installed them myself as I was putting new rims and didn't want anyone lifting up the Z but me.
Make sure that the installer you use knows how to lift a corvette.
