Sorry I'm getting in late on this one. My wife and I run a small but rapidly growing (!) goat dairy.
We use just electric to keep our goats in. Check out the portable woven electric nets sold by Premier 1 (google it). Given them a call too, they raise Boers behind electric.
Making cheese is exhorbitantly expensive, at least in MI. Grade A milk parlor, dedicated cheese kitchen, etc. Some friends set up a facility for $100k. Granted it was pretty big, but the facilities and equipment requirements are the same regardless of your size. Unless you've got a structure in place with a concrete floor grade to a drain, or you've got a LOT of money burning a hole in your pocket, I wouldn't even try.
We're finding just doing the milk end of things to be plenty profitable (and time consuming).
