UE: Any bar at begining of game, really starts at Luna with a decent combat rating though.
Voinian: Pax, decent combat rating needed as well.*
Miranu: Mira in the Mirava system. No requirements.
Zachit: Outpost Zachit, pretty good combat rating needed.
Zidagar: Prozdag-3, just go to the bar. No requirements I think.
Igzdari: Kitrak with a pretty good combat rating. Fast ship also needed.*
Azdgari: South Tip Station, pretty good combat rating needed again. A ship that can make it across the galaxy without refueling helps.
Human Renegades: Get a pretty bad legal rating in the Iothe system, then bribe them and land.*
*Somewhat low chances.
