Umm. Dire Wolf pelts, large fangs, Saurion tails and scales all sell well. So do the drops from Cyclopes's, Ogres, and Chimeras. Other that I don't have any idea how to make money quickly, if you have any quests you can do fast maybe do those.
Yeah, just go out hunting/exploring/questing. The meat will go sour on its own, and sometimes you can stumble across some large money sacks with 1k or 10k gold. Yesterday, I went from 30k to 80k, down to 50k from enhancing/buying, and all the way up to 180k (level 30).
OK I just grinded the cash and bught myself the full Swordsman armor set & weapon.
There's this quest in the capital's alehouse notice board called Trail Of corruption and it's next part Thanks Mislaid. These 2 quests are super easy as you just gotto go into the Fournival Manor and pick up 2 items from there. Easiest 100k gold you ever make lol.
Then go do a qust called Hobble The Foe in The Encampment. THat gives you a Hammer worth 140000.
That in addition to any looting and exploring + item selling you can do will easily get you the 250k + you need to buy the full Swordsman armor set.
