Going from 300 to 375 is very easy, but its going to take you as long, if not longer than it took to go from 1 to 300. Even if your skinning orange mobs, you'll only get a skill up every 5-7 successful skins.
 
Realistically, you could level up to 375 on the mobs around Hellfire Peninsula, but it's not the most efficient way. The following is what I believe to be a more efficient way to level it up.
 
 
Skinning 301 to 310
 
Hellboars around Hellfire Citadel in Hellfire Peninsula.
 
 
Skinning 311 to 330
 
Ravagers around Falcon Watch in Hellfire Peninsula.
 
 
Skinning 331 to 350
 
Talbuk's and Clefthoofs all over Nagrand. (you could just as easily continue skinning to 375 here if you want, as if wont take that much longer, than going to Netherstorm and skinning Drakes)
 
 
Skinning 351 to 375
 
Netherdrakes around Stormspire in Netherstorm or around Netherwing Fields in Shadowmoon Valley or Raptors and Wind Serpents around Blades Edge Mountains.
