thats your best bet..
but, i wouldnt make your own neck...i would buy a pre-made one.
cause, when you get into putting the truss rod in, and getting it the right length and all that stuff...its very tough...i wouldn't mess with the neck.
you can get guitar bodies already made from www.warmoth.com..they
but, since you have a woodmill, you could make your own..
but, what kind of music do you play? cause, pickup's matter on that..
