My ballie started building one but gave up... it should be pretty easy though, just buy all the components, carve out a peice of wood so they fit and you done. Acoustics don't even come into it.
GuitarForumsSA is the place to go - sure there are quite a few okes there doing this already.
I know that they have a list of Luthiers up there (Nationally) that you could maybe get in contact with.
Blocked at the office unfortunately.
