I was just wondering how much I could get for this, so I'd like your opinions.
If a game has a * next to it, that means I have unlocked every achievement.
=========================================================================================

Cod:

*CoD4| 10th prestige, everything unlocked legit, all DLC, mediocre K/D (1.7)

*WaW| 10th prestige, everything unlocked legit, all DLC, decent K/D (2.6)

*Mw2| 10th prestige legit, basically all challenges except one(impossible), 3.5 K/D, all DLC.

Black Ops 1| 14th Prestige lv. 50 (can prestige), all DLC, completely all easter eggs aside from moon, 2.4 K/D.

Mw3| 20th prestige legit, all difficult challenges, all DLC, 2.1 K/D.

*Black Ops 2| Prestige Master legit, all easter eggs, 4.3 K/D, all DLC, Masters #1, subset classes.

Ghosts| 8th prestige, all DLC, 1.6 K/D, REALLY DO NOT CARE FOR GHOSTS -.-

Adv Warfare| 15th prestige(not max level), 3.1 K/D, all DLC(atm).

-----------------------------------------------------------------------------------------

Other Information:

The gamertag is currently a semi-og but I am capable of changing it to a five letter og(Nice quality) as I have the money to do so.

Ten year tenure for gold, and currently on a semi new one year(expires in nine months).

Have a decent amount of OG, known players(Halo & Cod(comp sniping)/Portal freerunners, and feeders).

Also I have about 25 dollars on the account itself.

Almost 60k gamerscore.

Keep in mind I'm only thinking about selling this account, as xbox is feeling a bit repetitive at the moment.
As with needing the money to get by for college.

Thank you for your time!!
