You can always just sell materials to the merchants, some of them will buy them for much higher prices as indicated by a little star in the material menu, I've made like 200k from selling gems to the Gerudo Merchant who buys them for a crazy price.

As an aside, I think Sooga, in the right hands, is the most powerful character in the game if you can get the timings down on his counterattack, there's nothing you can't counter from what I've seen and he gets stronger the more counter tags you have active at once.
