A creditor returning his money, Need setting advice Options

[Smirnov]

I need some advice on a story I'm doing right now, it's a development going in the background of the game, which may have an impact on the player characters. Here's the story:

There is a former cop, nothing fancy or special. He has some investigation skills, some fighting ability, but nothing that would make him top tier at his field. At some point he get to be on the wrong side of the truck driven by cruel fate and ends up in a hospital without any limbs and with a few hours to live without life support for which he has no money to pay. At this point some smiling and very polite people appear in his ward an offer him a chance to live, which will need an extensive implantation (which he can't afford, but the generous gentlemen offer him a credit). Being drugged and clearly not in his mind, he agrees to their proposal. Some time later he leaves the hospital, perfectly healthy with new implants that boost him to the limit of his physical metahuman capacity, a shiny skillrig and owning a substantial sum of money to a corporation that took interest in him.

Now, how can a said corporation return their investment? I understand that if such a situation arose, no sane corporation would offer to spend money without knowing in advance how they would profit from it, but let's imagine in this case they had some other, non-profit concerns, and getting the money back is optional, but a highly desired option. The implants made the victim a capable fighter, but as I said, he is not top-tier. Still, it's his strongest point. So, how can his benefactors profit from it, assuming they want to get their money back fast and then start actually profiting? I thought along the lines of bounty hunting, but it's a rather slim line of income.
