COD 5 10th Prestige for Halo 3 50

I have a Tenth prestige in Call of Duty World at War and I would like to trade it for a halo 3 50 general, preferably hightest general I can get.

Has never played halo 3 on this account.

I will not go first but if needed i can get a middleman of my choice.
Those are the only conditions I have.

Thank you for Looking. ( Message me in this post)
