Around me, I was quoted $1k- $1500 for a 50A 14-50 install. 16ft from panel to outlet. Told them it was fot a compressor, but wanted to future proof it should someone want to put a charger in later. Had them quote me for 6/3 copper.
The one electrician I was going to use didn't change his bid when I told him 60A to a Tesla Wall connector. So at least I know they weren't charging a "Tesla Tax".
In the end, went with a friend of a friend who works for a large electric company. $700 total including 30ft of 6/3 copper. Used about 24 ft of it. He said it's running them about $6/ft currently.
We put it in the wall, and I did the sheet rock work afterwards.
