Re: "selected group of importers"..given access to make "certain types" of declarations,
A number of financial services have already opened up shop in Amsterdam...
Any cloggie worth his/her salt is anywhere from well-versed to fluent in english, and quite often also in a major secondary and/or tertiary language. Translation/intermediary services in almost any imaginable language are readily available, if you're not too fussy about "appearance" there's a ton of office space vacant, and you're sitting right on top of two fat international digital pipes, one of which goes straight to London.
What's not to like?
