Though I saw a similar profile made for the same task, I thought I'd upload mine as an alternative. It is not perfect, I'm not sure the graveyard ressurection points I made even work. I'm just trying to contribute what little I can.
I used this after I didn't want to lose my Bloodsail rep as I'm going for the insane title. It is set up to run a loop from the southern most camp of the Barrens Pirates. You get 2.5 rep per kill with Everlook, Gadgetzan and Booty Bay (12.5 for Longshore) through exalted and 5 rep with Ratchet (25 for Longshore) through Revered. I stopped at revered to go to Dire Maul for the keys and ogre suit.
I made this profile using GnomeTools. It is far from perfect, as I stated before. I would run it at night while I slept and I awoke every morning dead usually after anywhere between 2500 and 3000 kills. Something appeared to happen where I would go off course and end up in the water by the boat out there. If you're willing to not care about that, this will happily raise your rep in a few nights while you sleep. After all, whats gold.
