EDM stands for Electrical Discharge Machining . It is a far more precise form of electrical material removal, and does not use compressed air in a jet the way that a plasma cutter does. Totally different process.
The other people that you see that have done a porting job to their guns have access to a professional mill and training, or a friend that has training. This is not something that I would even CONSIDER trying with any of my guns, and I am generally up for trying almost any project myself.
