Is there an easier way to earn money?

[IanTheWizard]

I completed quest "Brigands' loot" (died a few times during that quest). But the reward is just 225 exp with no money.

At the moment, I need thousands of dollars to buy spells and wands.

Thin leathers (of young and adult boars) sell for only 4 dollars each. It's too slow and tiresome to earn thousands of dollars by killing 1000–2000 boars.

Any advice or hint would be appreciated.
