I would buy a bunch of green gear from the AH that comes from the outlands, it's not too expensive and it's probably better than anything you have including many blues.

if your miner or skinner is not to level 300 yet then you should work 100% of your time getting them there. Winterspring and the badlands just before the outland are good for the miner leveling ( probably the best place for miner leveling is the zone before the outlands, just do a circle around it without going into the demon area.

then I would move to the outlands and kill boars, if you can kill the stuff below the hellfire citidel in the trench you can get ( honor hold/ thralmar ) reputation to something like friendly or so.
If you can't go the outland directly yet then ask a warlock or a mage to transport your team there.
