The easiest way to make money is to not spend money. I know, it sounds absolutely ridiculous since you are trying to make cash to spend it on a Tormented Sword (100k +26ecto is quite a bit of cash), but it works. So many players get caught up in the "gimme gimme" attitude that they have no patience to build up the necessary funds for the gear that they want. If you save up the gold that you get while running quests and missions instead of spending it, you'll start to pile up cash to bankroll future purchases.
Go to
GuildWiki and check out the weapons offered by Collectors. You can find a max damage sword with whatever inscription you need (15^50 / 15^stance) that you can get by trading in 3-5 of a given collectible drop. It will take you around 15-30 minutes, depending on the drop you need, and you'll get other items to sell off while you're trying to farm up those collectibles.
This is how I outfit my characters before they've "earned their keep", so to speak. It saves tons of money, and teaches the patience needed to be a dedicated farmer (if that's your thing).
Hope it helps!
