Need to bore hell

From time to time, I need Norton or Triumph cylinders bored. Most I would trust "out of the box" are so backlogged that I might not live long enough to get the cylinders back. One that I used did a good job of boring but charged more than agreed and took three times as long as promised. I've written/left VM for two who have never responded.

So, does anyone know anyone reliable in the US that can and will bore Norton (or Triumph) cylinders and simply do a good, on-time job, for a reasonable price?

Here's a couple of respected shops here in SoCal.
Have no idea what it's like to do mail order with them.
Both are always busy....

Dan at F&G is good in Hollywood (as mentioned above), as is Richter Machining in Iowa.

Engine Dynamics in Petaluma, CA do stunning and honest work. See their website. Owner is a Brit. His Trident is on display in his shop.
But shipping barrels across country and back must be quite expensive.
