So, I know you said you weren't really looking for an in-lore source, but there is actually an organization of Bounty Hunters and covert "special forces" so to speak called Azeyma's Shields. In 1.0, the organization placed recruitment adds and hired skilled Adventurers from the Guild Registry. If you wanted to be currently or formerly affiliated with the Azeyma's Shields as an operative, that would give you lore cred.
As Chacha suggested, the Grand Companies would be another viable lore source, as they commission Hunter-scholars, which are essentially Bounty Hunters of beasts and men. Further along that, Ul'dah has always boasted a mercenary military, so it stands to reason they would also contract with Bounty Hunters.
Or you could just make your own company of Bounty Hunters and use Leves and Hunt Bills to fund your new growing organization. All work! ^^ Best of luck with it! Sounsyy may come to you someday needing a Bounty taken care of for the Maelstrom.
