I wasn't saying Gallup is bad or anything. Actually, I was paying you a complement. I think (acoustic building aside) it looks to be like you have the skillset already that they will be teaching. Unless your setups suck... but that I don't think you need to pay $6,500 for to learn. That you just need to do more of to learn.
Yes, I got to study under people, Todd of Greenridge guitars as well (where I got my acoustics knowledge). Yes they helped a lot. But mind you, this was not an 8-week classroom, etc. You learn through time, repetition, and not just knowledge transfer. I worked with Todd for over a year on my acoustic learning every in and out. Another girl that did the same after me (his second student) produced an equally quality and beautiful instrument. She then went to a class like you're going to and put out her second acoustic... nowhere NEAR as nice, putting it lightly. These are in/out learning places. You learn the basics, how to build fast, and then it's on you to learn to perfect your craft. At least this is what I get from all those I've talked to about these schools (*Note: not talking about Gallup in particular, just lutherie schools in general). Seems you already understand the fine detail and craft-ability parts of lutherie. You also already know electrics. I'd think you're better off putting that $6,500 in some new tools and jigs and going at an acoustic yourself. I'd be happy to answer any questions you might have as well as the OLF forum I'd imagine.

PS: Having gone through more business school training than I care to admit (entrepreneurship masters classes included) I'd discount anything you 'learn' about starting a business from the ground up in an 8-week setting. Especially one where you're doing a lot of other stuff.
