I agree, what kind of corral do you need? How big does it need to be? What kind have the horses been kept in in the past? If it is for broke horses, you might be able to do a double wire electric wire fence. I am unsure of the cost but you would only need posts, insulators, wire, and a (oh, I'm having a blonde moment...........) that thing that sends the shock down the wire, I want to say generator, but that's not right. LOL. However, if you have young or unbroken horses, you would need something a little more secure like metal panels or wood rails.
