+1 on the hiring people with disabilities.
I design for a large commercial manufacturer and we get a local supplier who have workers with intellectual and physical disabilities to construct some of our components. We utilize their ability to make carcasses for lounges etc, and they have a cnc and wood machining workshop.
Another avenue is contracting out work to suppliers much like a large factory like ours does. Do you have a specific design that you can produce drawings of and give to a wood machinist, steel fabricator, etc? Just watch your tolerances and make sure you make it very clear what you want.
If I was running a small business I would start with a decent home workshop and contract out whatever was too daunting for me to handle at home.
