Vince Cottone at Sound Brewing Systems is a great resource. I check his website at least three times a week, except lately there hasn't been much used equipment out there. But he has some excellent advice on starting a brewery.
His latest advice is almost a rant! But it is full of great points. I get emails all the time from people thinking of starting "small" and testing the waters. You have to read his advice at www.soundbrew.com on his "Nano-brewery" page. Not to throw cold water on anyone's plans, but every word rings true.
