Talc

Another infinate gold trick, travel to Kvatch, ride your horse into the middle of the camp there and up to the Orc merchant. While on the horse, sell your equipped weapon. You won't lose the weapon, but you will get the gold for it. Keep selling it to make that amount of money each time. No, this isn't a dirty trick to make you sell your good weapon, if in doubt then try it with a crappy weapon first. Remember though, it MUST BE EQUIPPED.
