HELP! Road Runner in prison, or any garage door repair guys out there?

The excuse was 'residential springs are 2 inch ID and I do not do commercial, or large ID springs" for two guys. The third guy gave me some of the Mafia Story. I got the low down today about the Mafia from a semi retired garage guy.
Yeah, I get it, those bigger diameter springs are a BEEEYOTCH to wind for 1 man, and lifting them is no picnic either. If you get desperate enough maybe the best alternative would be a new install.
