You could look here for a goat: www.goatworld.com/.  You could also check the craigslist in your area to search through the classified ads and see if they have a goat for sale.   On craigslist you can usually find just about anything you want, and the price is almost always reasonable.   Just make sure that wherever you find the goat, that you have the health verified, so that you won’t be paying money for an animal that is unhealthy.  All too often, people do not want to keep a pet that is ill, and they don’t want to pay expensive veterinarian bills.  Therefore, they put the animal up for sale, and if you buy it without first checking its health, you may have a sick animal and also, lose the money that you just paid this person. Make sure too, that you have the proper environment for a goat and that you will not be violating any city health codes by having a farm animal at your residence.
