Rees,
I think you are getting closer to the info needed. If you know for sure that the machine will only input 440 VAC 3phase and it requires about 10kVA input that is sufficient for an electrician to get started looking for a transformer. He will know that a 480 to 208 stepdown transformer can be turned around and used as a step up the other way and the kVA will get him into a family of transformers that will work. Expect a box the size of a small desk and weighing several hundred pounds to be stationed somewhere close by. If the power vault is indeed in the next room, that might be the best place for the transformer. (air cooled models are the best for your application) A custom transformer is not needed, there should be off the shelf devices that will do the job. He will likely do this anyway, but you want to make sure that the wiring is water and oil resistant and well grounded. Congratulations on a fine acquisition.
