Doubt you will sell the account at this price. I think that your best option would to be continue grinding the game and make your base a max town hall 9.
From a buyers perspective, it seems that you are a rushed town hall 9 with your low level walls, traps and defenses including your wizard towers and air defenses.

Another issue is the state of the game and its community. Clash of clans players are a dying breed and those who still enjoy the game have their personal accounts at a much higher level than yours.

My advice to you would be lower your price and try get rid of it as soon as possible, as its value will continue to decrease as time goes on.
