Your best bet is to get the quad Zoner bribes on Bethlehem in Pennsylvania, and then Corsair bribes once you're out in the Omicrons. I'm not sure how many multiples you can get in terms of Corsair bribes, though...
That will be NO.As far as I know there is none Order bribe.As Sprolf said,you can get Zoners and Corsairs bribes.
And you can just shoot a tones of nomads and Bounty Hunters...
Or do missions for the Order once they aren't red for you anymore. That should accelerate the process, I think. (Take it with a grain of salt, I've never made an Order char.)
