Custom case co. out of Ottawa. In addition to some of the best prices on Pelican and Storm cases I have seen, they do the custom foam cutting you are inquiring about. They do work for select Federal agencies and as such have many existing templates.
There is also Production Case Company out of Carp, ON. (Just outside Ottawa) Similar specialty capabilities and they will do work for civilian requirements.
Maybe not what you're looking for but I purchased a case with the 'pick and pluck' foam and when I had the form I wanted I sprayed it down with that liquid rubber in a rattle can.
YMMV
