Everyone knows Boba Fett. But to name the other bounty hunters, you'd have to be a pretty big geek (no shame in that, but it's true).
This is the problem you'll find if you start freelancing. There are very few Boba Fett-caliber freelancers in the industry. It's extremely hard to do award-winning work as a freelancer, because those aren't the assignments agencies typically give to freelancers. They're usually brought in to do supplement work. Or to fill a gap left by a departing team until the agency can hire someone else.
You can make a lot of money as a freelancer. And when you start interviewing, you should let agencies know you're open to doing freelance work (it beats sitting around waiting for the phone to ring). But unless you've already made a Boba Fett-sized name for yourself as an award-winner, you're going to be a 4LOM or a Dengar (again, no shame in that, but it's true).
GEEK CHECK: From left to right - Dengar, IG-88, Boba Fett, Bossk, 4LOM, Zuckus (out of frame). You don't want to be a freelancing Zuckus.
