What to do with old account?

I have this level 70 on outland that I've played for a few months, when prompted to sell him I have to sell him for 180 coins (Almost 200 Euros!), but honestly I would be happy with getting 10% of that just so I can boost a new character on Ice-crown from 1-80,

Is there any way to sell my character for less than what is default on the sell character form? I'm not sure why we can't choose our own sale price, or delete the character and receive MUCH less coins. I mean if you think it's worth 180coins, give me 20coins and sell it for 160coin profit!

the minimum price is based on his equip and, in case you select full inventory, what he has inside bags + Bank.

So to lower the price you can:
1. Select Equipment only
2. If the price is still too high you can put some of the equipped gear inside bag. So the price will go down because the buyer will not get it
