Information about selling character

Hi,so I need some advice, and my question is about selling one of my characters.
I mostly want to do it becouse im interested on buying Shadowmourne.
So I have a priest , I tried to put it for sell and says that I can sell it for 142 coins, I would like to know if that is good or I should ask for more?
Also says that I have to pay some coins,those coins,they will take it when someone will buy it,or before I put it for sell?
I will attach armory from my PJ http://armory.warmane.com/character/...ecrown/summary
Thanks.

To be able to put something for sell you have to be with premium account, People don't wanna pay for random non bis gear you would be able to sell it with boes on it and the non bis gear removed from it, boes doesnt add up to the price and the coins that warmane takes is after you sell something

If You want to know real value of Your character - its 30 coins. And You gotta be quite lucky
