Crafty Cash:
Here's an easy way to use the crafting system to make a ton of money when you're around level 10. Once you've got Gozen in the party and you've beaten the Demon Wolf, head to the crafting shop in Jade City. Buy a bunch of Hardbone Hilts and Steel Blades. You'll be able to use them together to create a Saber that sells for about twice the amount of the ingredients. Repeat to taste.
