I'm calling around for some sort of quotes to replace my failing circuit
breaker box and so far I've only received one estimate.

The price they quoted was about $2500 bucks roughly or $91/hour for their
work - including permit and inspection. No other electricians want to
release their hourly rate nor provide estimates. I'm not bitter about it,
just interested in how much money I'll have to secure to do this.

So if you had to guess, what would it cost to replace a non-grounded circuit
breaker with a grounded circuit breaker IF I SUPPLIED THE BREAKERS AND THE
PANEL.

Problem is it's a pain in rump and thats why you are getting the high
estimate. Keep looking.
