OK, so, I'm just giving you a heads up.
A Hitman Absolution Prime Gaming key isn't exactly going to snag you games that are worth proper coin right now. It's a game that was given away on GOG in the past, hence an abundance of keys given away online for free, and quite a few others who are trying to trade it like yourself.

But, if you're still wanting to trade it there's a dedicated thread for that here:

EDIT: Ahh, I see you found the thread by yourself. Good luck.
