A straightforward torsion spring swap on a door from this era takes a tech with the right wind cone and winding bars - the risk is the stored tension in the spring, not the part itself. Cable replacement usually gets done at the same visit if the tech is already pulling the drum off, since the labor to get back up there twice costs more than the few extra dollars in cable. Openers from the early 90s to mid-2000s are mostly chain-drive, which means a worn sprocket or a stripped gear kit is a parts-and-labor job, not a full opener swap, unless the circuit board itself has failed. We come from Everett, about 18 miles out, so the drive is part of the visit - there's no branch on Camano, and the quote accounts for that trip.
