Skinning

To powerlevel your skinning you don't need to crack open your piggy bank and buy loads of materials from the Auction House. Instead you get to run around for hours right clicking mobs and then selling the lootz on the AH. Right clicking (skinning) mobs you say??!! Yes, isn't that your favorite thing to do? There isn't much more to say than to just provide the best zones to run through and grab the skinning skill you want. You probably don't even need the guide, you can probably just remember where you saw beasts during a particular level span and increase your skinning skill that way.
