Soooo one of my first guides so far (nothing really big though :/ )
Its a kinda easy method.
Actually im in one of the servers where i can sell light leather for almost 2G a stack (middle leather costs only 50 s....dunno why )
Now comes the easy part get the latest glider beta or the latest stable version you like
and get one of the profiles where you can skin allooooooottttt of beasts (i prefer Elwynn forest&redridge mointain as alliance)
Now run the profile for ~2 hours and let him skin everything (filter out gray and white items with Lootfilter)
sell the leather on the auction house and buy some 10 space bags and do everything over and over again
you will come out with something like that
and you can see allready how much money i got with lvl 23 :O
