That's about $480, by the way.
Yes, this is what I was getting at. Here is the actual math (not directed at you, Randulo):
Premium pads and material run between $60 and $80, with higher costs than that for bari. I think tenor is more toward $80. Admission: I have never bothered to notate every bit of materials cost for any particular pitching and make/model. Premium pads are more expensive, now, than a lot of people think, at least in the US.
So figure for a tenor $80 off that $480, leaving $400.
For me, overhaul time is around 30 hours of labor, strictly on the clock. Sometimes it's more, sometimes it might be less. I doubt it is almost ever less, for me. Your guy(s) may be faster, or he may not wash the body and neck, you name it. No two people likely do the work exactly the same way.
Funny sidebar: there is a very well known tech -- I can say this without being controversial because he's no longer working, no longer in the industry -- and he watched everything I do very closely, and I used to do more weird (but IMO sensible) things than I do today, and back then I didn't do some critical things that I do today. One time a "repad" (this person did not do mechanical work, almost at all, came to me to be redone, and when I unpacked the horn I entered the twilight zone. This was a Mark VI alto. If the owner is reading, s/he may recall this. I could not for the life of me remember whether I had seen this horn before, but it seemed to be by my hand. There were numerous idiosyncratic things I do that were present on this horn that I've never seen anybody else do. But I could not see myself doing this job without doing the mechanical work, or with the pads that were installed. It took me 20-30 minutes to get over the shock. Clearly, this person was paying really close attention to any photos I made public, or had had my work come in. Nobody does the things that I was seeing, let alone in combination. I would bet there are other techs who had the same experience, coming across this person's work. Anyway...goofy sidebar about no two people do things the same way. That person, himself, was unique in probably copying so many other people so closely in peculiar ways. I am not b-----ing or complaining about him. I'm not wrong, and I'm complimented.
Anyway, you should have already done the math, casually. $400/30 hours is US$13.33/hr. Lower the labor time to 20 hours -- very modest for an overhaul -- and you're now at $20/hr. Only someone who is not really making a living at their job can work at that rate. Good luck not ending up homeless if that's your income, even in a rural area, and you are raising a family. If your tech is expert and doing so, you should worship the ground s/he walks on and be very, very kind to that person, because s/he deserves it.
