Great idea and nice work. I friend did the same thing years ago when he was starting his own mold shop. Everything was in his garage, on dollies, and two rows of 220 v. 3 phase busway were suspended from the ceiling. Worked out OK until he was able to afford commercial property.
Thanks for the inspiration - I've got the same problem.
