Mike,
You are exactly right. The $250,000.00 figure is just to get started with the basic machines. Material, labor, insurance and misc. would be well above that.
Glue mixing and layup machines, ovens, grinders and cutters do not come with a low price tag.
I remember when I was in the shaft business just the cutting, milling and grinding machines set me back well over $30,000.00 and that wasn't counting all the machine shop time required to get those machines to do what I wanted them to do.
