I have an account with Warlords of Draenor that I am the original owner of. I haven't used it for a while, and now I'm finally getting around to selling it.
I have tons of rare and expensive pets worth well over 100k. Many of these are level 25, and there is a total of 488 unique pets.
I have most professions at or above 600.
I also have a ton of expensive mounts, like jewelled onyx panther, sky golem, sandstone drake, and a ton of exalted rep and achievement mounts.
I have about 30k in gold.
My 3 level 100 characters each have a very built up garrison that pulls in thousands of gold a day.
I have just about all of the levelling heirlooms, including the mount that can be used at level 1.
This has been my main and only account for the many years I've played WoW, so it has all kinds of rare achievements and items.
Go ahead and ask for any information, I'm new to this stuff and don't know what else to list.
Taking offers.
I have one character of every class. Level 100 Warlock, 100 Hunter, 100 Paladin, 90 Monk, 90 Mage, 88 Rogue, 88 Priest, 87 Warrior, 86 Druid, 86 Shaman, 86 Death Knight.

Still for sale (1/11/16) I'm going way down on the price now, as I am in a bad bind with money right now. You could probably buy this account and split up the characters to make a huge profit off of me. I'm fine with that though, as I need it ASAP.
