If I were to contract a company to make a Spartan suit for me, who would I need permissions from? and how do I obtain this?
you wouldnt need permission the armor is not trademarked so you can create it and where it around all you want. now if you are interested in purchasing armor I might recommend the 405th they are experts in creating spartan armor.
this is some of the things they created. note that the really good spartan armor is their creations
