I have "toons" that are Skinner, Herbalist and Skinner, Miner in game

Skinner as you will be killing many skin-able mobs early on, and either Herbalist or Miner as the radar marker conflicts - you can not have WOW Gold both an Herbalist and Miner radar blip on. I have "toons" that are Skinner, Herbalist and Skinner, Miner.

I think the gold generated is a little better as a Miner, so you need to ues wow gold buy that, but if you choose a dark-elf as a race go herbalist as the starting area has no mining resources - there may be an equivalent horde race.

Keep notes of how much a stack of resources such as light leather from skinning, copper ore from mining, silver-leaf and peace-blossom from herbalism.

Check the Auction House prices using the search facility and take note of the starting and buyout prices for the stacks of resources you are selling. Many items have a buy-out price up to 10-20 times the price an NPC vendor are buying wow gold from you.

The best part about this quest is that it is repeatable, meaning you can do it over and over again. Granted the exp reward does drop after the initial turn in but an extra 390 exp while grinding always helps.
