Growing up we had a flock of about 35, mostly for wool production, but also for meat. I might be able to answer a few questions although I don't know anything about haired sheep. We never used electric fences because our animals' wool was too thick to allow them to work. Even barbed wire acts more like a suggestion than a boundary if you let it get the least bit slack. The wool starts to build up like felt on the barbs.
Are there vets in the area who are familiar with sheep? We had a farm vet that made house calls. There were just a few farms with sheep near us, so he learned as he went. (He turned out quite good, and was a nice guy to boot). The local Co-Op carried no meds for sheep, so everything came from the vet or mail order.
As an aside, major wool producers cull back sheep because they want a uniform product. Craft type weavers and spinners go ape shit over black wool and pay a high dollar for some types, so acquiring someone else's rejects can be a cost effective way to start/increase a flock. The meat tastes the same.
