However, it also makes sense that if you get really good at smithing and enchanting, that people would come to buy your services in that as well. They can order an ornate golden sword with a marble hilt, and you need to go out and craft it, and then make money for it. After all, if you're a master smith, doesn't it make sense that people would pay you for your work?
Same can be said for magical equipment and your enchanting skill.
