I'd actually focus more on reputation for delivering results than accreditation. Accreditation is a massive bureaucratic nightmare and I'm not sure it's worth it. For access to Title IV, maybe, but it's going to seriously cost you in other ways, slowing you down on a 1000 fronts.

I don't think you can beat the current universities by playing the game by the rules they've set up to manage their competition. Just seems like you've lost before you've even started.
