Selling 2 accounts one with 3 years and 9 months on other

Both accounts have never played a game and have no Microsoft Points on them. I was stupid and put my codes on accounts when it would have been easier to sell codes.

The first account has gold until 3/10/2013. *3 Years*

The second account has gold until 12/11/2010. *9 Months*

I am not sure how much I want to for them so PM to offer for either one.
