Am I asking too much?

Maybe he has no idea how to do it, or is just a male sexual organ.

I did enjoy the last few month's journey of tinkering with a Garrard.
Not as great a yours but has a DAS plinth, some new parts - all installed by myself.
Dr Feickert alignment tool helped with a vintage cart alignment.
Used Schroeder and rebuild vintage Ortofon arm.
I had some issues with the Scroeder set-up so email Frank in Germany and got several email responses what to look at (as well as several AG pointers).
It is a 10+ year old arm but he still happy to provide advice as well as his distributor in France, despite the fat that I got the arm privately.
So, customer service is not too dead...as some others pointed out above.
Too bad you did not clarify all the details prior to purchase. We unfortunately cannot "assume good service" anymore.
A few good videos on Youtube and many helpful folks here on AG and AK can help you set it up correctly. If you get some set-up tools (test LP, Fozgometer and or software from several folks like DR. Feickert and others) for the same money you would spend with this dealer you are set up for the future.
Enjoy the music and the one way ticket we all have!

Perhaps this B&M dealer really doesn't have the expertise that he needs to set up a cartridge like a Koetsu! If that is the case, he would be wise to disclose that to you...OTOH, he did say he would do it at full price, which leads me to question his business acumen. 
Koetsu's enjoy an enormous mark-up in this country. If you look at some of the Japanese audio sites, you can see the same models for mere fractions of what we are expected to pay in the US. The middle man is wringing his hands in glee when these cartridges ( and a lot of other Japanese sourced models as well) get sold here through a US dealer. 
Yes, i am aware that they have to stand behind the product and so forth, BUT the additional costs of getting the cartridge from Japan to here, plus the dealer servicing cannot explain the mark-up! IMHO.

”Too bad you did not clarify all the details prior to purchase”

what are you talking about? blame the customer/victim??  Please re-read the email trail. 

This is peak A’gon forum. All we need now is the guy who tunes his toaster to his ears and the obligatory “are you still an audiophile if you can’t .....”
