Cutting jade, or even opal, is ok xp for crafting and profit. For magic and smithing I would make money by the best means you have and buy nats and gold ore and use Superheat, it's fast xp in both. 120k+ xp/hr in both skills. You can high alch for profit, I spent 5 mins looking at tip.it item database to find an item I could alch with ok profit 2 weeks ago, suggest you do the same. But then you will be stuck with either very slow xp with c'balls or an expensive way to train smithing, so I highly recommend the superheat with gauntlets and make the money from something else.
