Where do u go to get the profession mining?
For Horde: Razor Hill and in Orgrimar.
For Alliance: Iron Forge or Stormwind (I think)
Hope it helps also I'd do Mining and black smithing or mining and enginearing because
1. they go well together
2. With black smithing you'll be able to make armour for not only your self maybe but others then sell it on AH for $
3. With enginearing you'll make things usefull like the epic flying mount (At 300 sum) and also very good Head equips (low level: Flying tiger goggles)
