Thank you all for the input. The outlet will be located ~50 ft from the main breaker box. It's a fairly difficult run in the basement - limited access - very tight. It's going next to the basement door so that I can get the stick welder outside to weld - can't weld inside the basement. So about 50 ft of 8 gauge.
I have used these guys before and was satisifed with their work - most recently to install a whole house generator hookup with interlock switch - that I attach when needed to a portable 7KVA generator.
I haven't been getting multiple quotes on these small jobs and was just curious if I was being charged the going rate.
The good news is they can come back Thursday to do the work so I'll be welding this weekend. :-)
