Call to armsOi, you there, yes you that git with ur 'ead on wrong. The Jolly Ork wants you. So sign on up and become a freebooter today!
No self respectin' Ork is paid ta fight. Wot I need some git tellin' me where to scrap when I can just krump em' and take his bitz dat he was gonna pay me wif anyways?
What kinda ork wouldn't like to get payed to fight. Especially for an ork who ain't used to losing. Trust me you couldn't krump ole kaptin Badrukk http://warhammer40k.wikia.com/wiki/Badrukk
Don't see why anyone would think Freebooters would need to be paid first. They're ork space pirates, you fly around in your spacey hulk and board other ships for dakka and slaves. Then trade them off to other people for more dakka and junk for yourself. Would be pretty fun to be.
Freebooters are free spirits. They do whatever the zog they want and don't let any boss tell em what to do...except for the captain of course.
Yes, since it'd mean I would get to play an ork dressed as a futuristic space pirate an ork dressed as a futuristic space pirate
