Plugin Request TradeSystem Plugin

Name of plugin:
TradeSystem
Info
I'd like a plugin to be made that will allow players to trade with each other. Items can be traded in return for money or an item and vice versa. Players can start a trade, accept a trade, counter a trade and decline a trade.

Commands:
/trade <Player> <Quantity of item to be traded> <Item name/Money> <Quantity of requested item> <Requested item name/Money>
/trade counteroffer <Quantity of item to be traded> <Item name/Money> <Quantity of requested item> <Requested item name/Requested money>
/trade accept - Accept a trade from a player.
/trade decline - Decline a trade from a player.
/trade mute <Player> - For staff to mute a player that may be abusing the trade command in any way.
/trade ignore <Player> - Ignore trades from this player.
Permissions:
trade.start - Gives player access to /trade, /trade counteroffer, /trade ignore, /trade accept, /trade decline
trade.* - Gives player access to /trade, /trade counteroffer, /trade ignore, /trade accept, /trade decline and /trade mute
Version:
I'd like the plugin to be made for 1.8.4 please.
