Thanks for the feedback

Flex hone is what you need. I keep one in my tool stash. A flex hone spun in a hand drill will deburr and smooth the seat tube ID. You will get a very small diameter increase if you get too carried away with it.

Is honing something that the typically shop is capable of?

Call up your local shops before taking your bike in. Some shops do Flex honing, Dropout alignment, rivnuts, Etc. Other shops don't do any framework

Might also look at a brake hone. Its more likely to give you a straight and cylindrical bore inside the tube.
