I have a local shop "superb mech", he also knows I wrench my own stuff. Yet I throw him bones, and I also throw him stuff I am 'not into doing'.
He knows I ripped apart my bb30, cleaned lubed and put it back together on my al synapse frame, because I put it together better than factory and front derailleur was out whack. So paid him to adjust.
Fast forward for the super six with hollowgram blah.... I didnt even mess with it. I just took it to him straight away.
He started dragging feet....
Long story short , something I had said. Or my tone, or how I said it put him on edge. As in I tried, I screwed it up, I dropped it off to make him responsible for it. Regardless I stoppedvin for coffee next door, then talked to him. Assured him I never touched it. Just factory dry and creaking.
Next day he had it done.
Point being, I can see a shop dragging feet on certain jobs if they think they will be out the money for frame damage. some are barely scraping by as is, let alone being out frame cost on a $20 job.
Risk vs reward....
I really have no idea your /shop situation.
I'd just advise dropping in, in person.
