Easy Money!
For quick bucks, go to story, and do the second part in sword haven, well, if you haven't beaten this part of the story you can reach portal undead by the map.
At the first part, there is this lady named Dawn. Do her quest, Fire Gem, and get the Burn it Down after beatting the quest. Sell the staff for a whopping 12k! i have seen people write that it is worth 200k... that just means 200k within about 1-2 hours!
Just keep doing the quest, and selling the staff over and over till you got what you want.
