Anyone local able to ream a BB92 shell?

I'm looking for a shop or framebuilder in the Bay Area (I'm in Redwood City) who has a Park 744 reamer or other way to ream and face a BB92 shell. It's an odd request, and none of the shops I've called have the tool. Anyone know a place that has one?

I got a carbon frame to build up for my son and it has an aluminum BB92 bottom bracket shell. The kid-sized cranks I have are made for BB86 (or any other road bike standard), so I need to narrow the shell by 2-3mm on each side. There is plenty of aluminum shell sticking out from both sides of the carbon to do it. Facing the frame is relatively straight forward, but I'll also need the 42mm internal hole reamed out a little deeper, or I won't be able to press in the BB bearings far enough.

I was trying to save money on this build, but I'm almost at the point where I'll buy the tool for a shop in exchange for doing the work for me.

Appreciate anyone's help or ideas. I'm also in Truckee pretty frequently, so Tahoe area shops are also a possibility.

Call Tom at Velotech in Palo Alto and see if he can help you. He's the best mechanic I know in the area and might be able to help you.
