No, do NOT do what Carlos said in the post above. If we're to go on that many LGD-type breeds are giant wussies until they hit 15-24 months, if there is any kind of guarding instinct in him doing the boogyman/hide-n-seek/runaway stuff will likely cause more of a problem than good. He's already acting fearful and getting him to act aggressively to get people to go away will only create a dog that's fear-aggressive. He'll likely still be fearful of most everyone but acting forward instead of hiding. I think he needs to be socialized and exposed to as many pleasant situations and people as possible. Only after he has come out of his shell and being friendly in safe situations should there be any kind of agitation work done... That said, I think that you simply got a $hitty dog from a $hitty breeder. You got duped. Sorry about your luck.
