Nah, its not good money, its poor money, its very costly to get to the area where you get the contract too, its costly to buy the weapons, its costly to buy the armor, ammo, guides, etc, & if you are ever captured, consider yourself dead, most of the time, the country you have the contract with will not go after you to make a rescue, heck, most of the time if you are injured, they wont even pick you up & carry you out, so its best to go in multiple squads where you can have someone watch your back.
You make depending on what you do, probably only a few hundred to a few thousand dollars off of it, in the countries money that you get the contract with, so you would need to later find a bank to get it exchanged.
Now if your lucky enough to bring in a big guy with a nice bounty on his head, they you will make a lot of money, but it would be rare that you would actually find them, let alone if you did, you would probably die trying to capture or kill him (talking about Terrorists here, not local Bounties.)
The Laws are different depending on which kind of bounty it is on, a terrorist bounty has little to no rules, but a local bounty has so many rules stacked on each other, its almost impossible to operate.
Thats why I prefer Merc work to BH work anyday. Local Bounties are normaly bail jumpers anyway, so they are most of the time not too dangerous, its how you have to bring them in thats the danger.
All ive got to say to all of the budding BH's, read the fine print, if it says to bring him in alive or dead, dont kill them unless its in self defense, use something more along the lines of nerve toxin to paralize them, then inject the antidote right when turning them in. Remember, they say to bring him in alive, not in what condition. ^^"
