Actually, there's companies that will pay you quite well for your gold. The best prices actually come from Chinese websites, which puts you at a disadvantage. Sites like pusada.com only source gold from Western players as a last resort. That's one reason they rarely buy, and the prices are bad. (coming up, I'll show you were to get the best sell prices online, and from an English site!)
Over the last several days, prices have been recovering, and there's VERY good news right now because with the latest patch, Blizzard did some updates to it's security system (really tightened the screws this time) which is going to stop the flow of gold from stolen accounts. It'll go down to at least 20% of what it used to be. That means legit gold, (like yours) is going to go up in value and continue to climb for the next few weeks as the black gold dries up and stays dry.
There is one site where you can sell at player to player and get prices, but you'll also be delivering to the end buyers. A little inconvenient since you have to be available, but you'll get paid better AND have a higher safety margin which mans less losses from bannings for you. Go to playerauctions.com and you're set.
Undercut other merchants and your offer will float at the top.
They've got a good items economy started there as well, so consider farming items. Way safer to deliver than gold.
