I would say I make 25-30 WOW GOLD a day in about an hour.
If you do decide to produce items to sell then always keep your eyes open on the AH for cheap mats. I never buy a stack of Thorium Bars for more than 6g, ghost mushrooms for more than 60s each, Dense stone for more than 2g50s a stack. When I see them on AH at these prices I snap them up because I know the prices will go up soon. This maximizes profits on the items you produce to sell. Obviously these prices are likely to be different on your server.
It is useful to have a gathering skill - either Mining or Herbalism. With the current prices of Dreamfoil, Silversage and Gromsblood I would recommend herbalism.
It is also useful to check certain items in the AH for low prices. I often buy stacks of Major mana potions for 10g and resell them for 15g for example. There are many other items that this can be done with.
On average I would say I make 25-30 WOW GOLD a day in about an hour just by doing all these things. The situation may well be different on your server but just spend a bit of time looking at what sells well in the auction house and you should figure something out.
