Cylinder wall damage: who can fix it?

[Dave Brady <brady@fas.harvard.edu>]

I went to put the head back on my '92 S4, after having TAP's head
treatment (three-angle valve job, port and polish), and having a local
shop fix the cross threaded #5 spark plug.

Now I discover the bad news:  the #5 cylinder wall has been been
significantly scraped.  There's probably a total area of 40 sq. mm.
that's damaged, in three different spots.  These areas have a
concrete-like feel to them.

I'm stuck; I've neither the tools nor the knowledge to remove and repair
the block.

Anyone know a reputable flatbed company in Rhode Island/southeastern
Massachusetts, and/or a shop that can repair the damage?

(At least I won't have to worry about my engine when this is all over!!)

Thanks!

Dave
