Pet Pigs

Hi guys! I am thinking about buying a pig. Not a ginuea pig, but an actual farm type pig. I heard they make really good pets, but I want to be sure before I buy one if it's a good idea. Is there anyone on here who has one, or has owned one in the past that could give me any advice? I'm curious to know what sort of things to feed it, and how often they need to eat, etc. Also any info regarding price and where I can get one would be greatly appreciated as well. Thank a lot guys!
