I used to use Superior Weave about 20 plus years ago when I was living in NYC. They were pretty reasonable and I could run my stuff into their 'offices'.
I called them about two years ago to get a quote for a pair of gray flannel pants w/ a 1/8th inch hole. The quote was $150. And that was from the owner. Outrageous.
I eventually found a woman in the midwest who trained out of work women to microweave. She was extremely reasonable. I think the cost was more like $50.00 for the 1/8th inch repair. She was not as great as Superior I have to admit, but w/o knowing and looking closely, you'd never be able to tell there had been a repair. I unfortunately cannot find the name of the place I used. But the moral of the story is there are more then two companies that provide this service.
