How much Warcraft account could sell for?

Account has just been sitting. Tonns are as follows Alli: 63 human warlock &19 night elf rogue. Horde: 80 blood elf warlock, 47 blood elf rogue, 65 blood elf death knight. 80 has gear from ToC and VoA currently at level 80 with 525 herbalism and mining max rest and is a GM of my guild (most people left though due to inactivity). Guild has guild bank with 5 tabs various crafting mats and 7k gold. Any help with the amount I could get is greatly appreciated http://us.battle.net/wow/en/character/suramar/Keiralys/simple
