Plans for a Baritone Acoustic 8 strings

[Spear Destiny]

Hello All,
Plans for a Baritone Acoustic 8 strings: Anyone know where I'd get them?
I've been scearching the internet looking for plans for a 8 strings baritone acoustic guitar and the only set I can find is on www.cadguitarplans.com. These plans are for a standard body guitar and I would prefer to build a cutaway bodied guitar. They also seem a bit on the expensive side when compared to (non-baritone) plans available elsewhere on the internet. Does anyone know if there is anywhere else I might find what I am looking for? Any info / help would be greatly appreciated.
Please helpm me
