you are in luck, i guess. - your choice would be the [SA] ( south alliance ). they represent the liberty navy and the military power of liberty in general. - you should check the factions message boards for someone to contact in a PM - or you can prolly just ask someone ingame to guide you to the source you need.
from what i hear ( i am not part of the faction ) - the liberty lawfuls are allways happy about new apps that are willing to join and RP - gtg:)
