That's fine, just get the character profile posted and we'll go from there. I can better advise on where you need to elaborate and such when I actually see it put together and posted.
That depends. There are no major bounty hunter groups, so people who play as bounty hunters are often independent and work on their own. However, the Rebellion and Hutt Cartel factions have places for bounty hunters, if you want to join either of those.
Hi there, welcome! To be a rogue or former Jedi or Sith, you'd first need to ask the leader of the faction the character was once part of. Ruthless is the Jedi faction leader, and Sreeya and Rom are the Sith FLs.
