I would recommend someone on here, but whovever you get to do it, ask them about how they plan to re weld the cut tubes. Weld quality is key to getting a good job done and uniform weld application is how the axle stays true without any excessive straightening.
When i do mine i go over the top with accuracy and weld quality/post weld inspections. The weld set up is a single vee butt weld
I do MPI (magnaflux) for any sub surface cracking in the parent metal following flush sanding and get my old mate to do 3 xray shots of it to provide a record of the weld and confirm the quality of the penetration bead on the inside of the tube.
I only use tig for the welding as its a high dilution process for better penetration. During all welding passes (normally 3) i do dimension checks for alignment and balance each weld to counteract any distortion from previous passes. Never had to straighten 1 yet.

ITS NOT WHAT YOU DRIVE ITS HOW GOOD YOU LOOK IN IT
Having mine done at Hausers he doesn't cut half shafts , buys new in from the states to size needed , does the case in a jig . costs more but safe
I agree, no cutting and welding of driveshafts for me either.
The cutting and welding i mentioned related to the axle tube not half shafts.
And i would ask the same welding questions of hauser too. A good outfit should have no issue answering those sort of technical questions to be fair
Steve large, large engineering in Kent did my 9" and it was a great job, I supplied custom 4 link brackets and new ends and he did the rest. all done in a jig and was spot on.
Looks like the OP has done one.
From what I've seen it is a real engineering feat to achieve so would use recommended as above.
Had a new bespoke 9" from Hauser and one of the off the shelf Strange halfshafts was 1/2" too long
John Sleath does em up north.
Mine Steve Large did after he had it powder coated
If you have a proving bar with the dummy bearing set up its a cakewalk there is no voo doo in shortening an axle casing, We did mine in a cow shed in '92. Welding is important
