I'm also really excited to see you do this. It's such a gutsy move to launch a company, let alone a guitar manufacturing business. Kudos to you!
I've also experienced moves like this before with a small engineering firm that did fabrication. We moved three times to progressively larger spaces, which involved relocating an office, IT, woodshop, machine shop, paint room, clean room, compressors, freezers, warming ovens, an industrial autoclave, and more.
It'll feel so good when you get everything up and running!
