I’ve been interested in building some of these awesome machines for a while, but I just don’t have all the equipment needed to build em. It’d be great if someone could point me in the right direction to find a builder in the United States (preferably eastern US; Virginia, North Carolina, etc.), or if someone could give me some tips on how to find help locally. Any advice or leads would be helpful 
Thank you all, so much!
Welcome to Precious Plastic @skipper1234
I suggest you to contact kmoore@iml-mfg.com and timmy_martin@icloud.com by email, they worked together to adapt the machine units to use Imperial measures, and they should be able to sell you a shredder as well. They are based on Dallas, but shipping the machine to Virginia should not be a problem.
Also, here are a few contacts from Virginia who might help you with your project:

In case you are still interested, one of our forum members converted the shredder drawings to imperial units. No one have tested cutting a shredder with his drawings yet but theoretically, they should work just fine. More info here:
