I'm a fan of "if you want to do it yourself, go ahead" but as has been mentioned above, it does take a bit of skill and equipment to do shaft pulls and then install. Only fair that you get charged for the service.
I do all my own re-grippings now, and plan to get into reshafting ... but in the meantime I certainly wouldn't trust a 4th grader to reshaft my $400+ driver.
sort of agree, somebody who knows what they are doing can make it look perfect, but to install a shaft really only involves mixing the epoxy and installing a ferrule, and jamming the shaft in the head, and waiting for it to dry, I would start with some things that don't matter, an old 3 wood or a wedge, I wouldn't pay for that service anymore after I have been doing it for a while, But Like I said to save a shaft It might be a good to pay for somebody to extract it, so you don't accidentally break the shaft, an extractor is like 150 bucks, I want to get one, other stuff is pretty easy, once you've done it a couple of times.
