Well, most of us here probably can agree with that, but you might find yourself out a few thousand in tools and a few years in time before you reach the level of being able to knock out something of really high quality.
So for what he was asking, for a once-off shot, a luthier (a good one with credentials and references BTW) would be the way to go, and I'll have to disagree with GM.
A good luthier will take those same parts and build a very high-quality, well-playing, valuable, beautiful INSTRUMENT out of those parts.
An amateur could take those same parts and build a pile of unplayable poop with them.
A seasoned luthier who's been at it for years and years will know things that some amateur just buying the raw parts would be -completely- clueless of, and if all you want is -one- incredibly good guitar, it's those intangibles that a seasoned luthier brings to the table that make it very worthwhile to hire one and do your 'one' for you.
That's why I stated it so matter-of-factly, there's no contest really.
i noticed you said "poop"
save that for the poop forum
