My new night elf hunter quintet hit level 30 last night and can now learn to ride. The problem is they only have about two gold each. I've perhaps unwisely been sharding BoE drops instead of selling them so far, and although I've stopped that and now sell them, I'm still a long way off the 45G needed (on each char) to train riding and buy mounts.

Does anyone have any suggestions on the quickest way to earn gold at level 30? Repeated instance farming? Any specific non-instance mobs that drop good gold?
