If Boba was still in business, and somebody needed someone found, he's probably the one you call first. And bounty hunters work for anyone who's paying, not just the bad guys.

Are you basing that on something written about him being the best in the galaxy? Because IMO the only thing that should be relied upon is what we SEE in a movie. And what we see is him hired alongside other bounty hunters with no preferential treatment, happening to be the one who gets lucky, and then going out like a bitch in the next movie. Doesn't immediately scream "the one you call first" IMO.
