First of all, this guide was wrotten by jordash.
Well welcome to my guide I have been keeping a couple of these tricks hidden to myself so now I'm gonna reveal them .
#1. [Light Feather's],
As a horde I made around a lot of gold while doing
(Thottbot World of Warcraft: Quest: Test of Endurance).
In this quest you will go into a cave and there will be a 3 box's which you must open and when you do 3 waves of harpies will spawn and come after you and of course they all drop light feather's.Not only that the box's respawn rather quickly.
With this technique I was able to farm 20-40 feather's every 20 minutes or 60-120 feather's in an hour.

Farming light feather's as an alliance is a lot slower then horde since they can't get the quest above.
Type #2 : The boomkin in darkshore are only around level 13 so you'll have no trouble downing these druid's errr... mobs and they have a pretty high drop rate for such low level's.
I'd recommend this to alliance since this is the best place to farm them other then barrens where you would get ganked to kingdom come.

Type #3: Credits to someone for this I can't remember though >.< .
The the second good way for low level horde is to go to barrens and start grinding out the plainstriders there.
I found this a great place since there's a pretty high droprate for greens and you may be lucky to get the deviate delight recipe which sells for alot of gold ( If your a low level it's a lot ).
#2: Limited Recipe Items.
One of the ways I've found profitable is to buy recipes.
People are lazy and don't want bother with thottbot or take the time to travel somewhere.
A great example is ....
SHADOW OIL RECIPE!
Buy price=15s
AH price=4g
Profit=3g85s
In Duskwood in Raven Hill there are 2 buildings that have upstairs. The Inn is one and another non descript building west of it. Upstairs is a goblin alchemy vendor who sells the limited purchase recipe for it.
I'm not sure If he's only alliance though, and I guess a horde rogue could sneak in and sneak out if they wanted to.
#3 Copper farming.
Farming copper is a great way to make money at low level's since alot of twinks are raising there engineering,
here are some maps for both horde and alliance copper farming.
#4 Secret Pets.
Secret pets are great way's to getting gold and sell for tons on my server, one of the best one's is "White Kitten" which is from Lil timmy who wanders around stormwind canals, a nice list of rare pets is http://www.mmowned.com/forums/wow-gu...cret-pets.html
(Thanks Violetstorm).
Well These are the best ones I can think of right now I'll try to edit this whenever I get a new idea.
