How To Get Bounty Hunters In Lego Star Wars The Complete Saga?

I have the game Lego Star Wars The Complete Saga for ps3 and I need to know what all the bounty hunter names are and how to get them. I’m trying to get bounty hunter missions unlocked and I don’t know how to get all the bounty hunters.
