Seems that scammers are about, if you add me on Skype, do not ask for the link to the profile, I will automatically block you. The reason being, how do I know if you are an employee of Steam and now do I know you are going to report me or not if the sale goes sour.
I do have a retail key for Black Ops 2 and will provide it along with the new email address / password and steam account login /password upon payment. There are no acceptations to this. I also ask that upon paypal payment, you can send the money to me as buying something (not family or friends) and I will have to pay the fees, this helps insure that you can not request a payment back after getting the account info.
