Forgot until I saw some later posts, some places will charge a bore for every half millimeter so if your going 3mm OS you get charged 6 bores per hole less the 'set-up' fee or about $50.00 for first one and $10~$15 per 0.5mm after that.
That's exactly what one of the shops told me. It makes sense, but it sucks when your the one paying!
I found a guy that does cyl boring/sleeving out of garage. He talked the talk- telling me how he matches a piston to a specific cyl (clearance wise), asking me what exact wall clearance I want, what type of finish, etc etc. He quoted me $45 a hole, so I dropped it off this morning.
When I pulled up and saw a Goldwing in the driveway along with a bunch of small engine blocks already machined out, I knew I found the right guy.......... at least I hope so!
