I don't think it is a one stop shop solution. Diversify your sale items and you'll get more sales over all.

So turn some of the wood/iron into arrows; turn some of the iron into ingots; sell some of the iron raw; all of these will target different types of buyers. You can't imagine what people want to buy and why - just look at ebay! So sell all the bits and you'll get more flow. Just like mexican water through a first time tourist. wooosha!

What makes a man turn neutral? Lust for gold? Power? Or were you just born with a heart full of neutrality?
