Paying for custom dies without the rifle chamber reamer is a waste of money.
Sizer made on rifle case is a half measure. Fitted bullet seater is the other 50 % that is as important.
We do that for benchrest rigs but, in my opinion, unnecessary for other type of shooting. It will create problems because of reduced tolerances. Today competition dies set are already more than what most shooter need.

Or you can send them a reamer print.
Fired brass vs reamer print is the root problem with custom dies.
The chamber is not necessarily reflective of the reamer print. There are reamer tolerances and individual machining tolerances that affect the machined chamber diameter.
The most accurate method is certainly using fired cases, no question. But then you are left to hope your next chambering job is done the same way.
If it's not, the cost will certainly add up if you get new dies every time you chamber a new barrel. In reality if the gunsmith is using a floating reamer head, probably of little concern. But if gunsmith 1 uses fixed reamer and gunsmith 2 uses floating head, you will almost certainly have a mismatch.
On the other hand if you don't use custom dies then the spread is even worse.

All this input is very valuable. Meaningless for me since I just use factory dies and my PR rigs shoot way better than I can hold them especially with my barrels like IBI, Benchmark, and McLennan (Rob) in Wyevale, ON.
My contact thanks all of you. I’ve been cutting and pasting all your suggestions and then forwarding them to him and his crew.
All good learning for me too. Just shows how much I don’t know! We are forever learners in the craft! I stole that from Phil Velayo of the Modern Day Sniper podcast. LOL

What chamber are they going to be building?
That will have an affect if you even need custom dies

A lot of great points. Like has been mentioned a custom die is of no benefit unless you have your own chamber reamer. Paying the money for a custom die for a factory chamber or possibly a chamber where your gunsmiths reamer is used I feel is a waste of money.
And that’s exactly what I’m taking away and passing on to my people who asked me. Thanks everyone for your excellent input. As usual, this forum can be a great source of information based on experience!
