For future reference, I think I've found a pretty solid place to do Knight Investigator badges if I ever want them: http://www.shieldspride.com/
It would end up costing around $500 for a couple of them, but it might be worth it just for the total amusement. I would end up having to ask them if they can turn the 7-point stars so that they are point-up when they do the stamp and imprinting, but the silver ones are close enough to pass cursory muster.
So... who wants to be a detective?
