Simple Message Plugin Needed!

Hi, I REALLY need a plugin that simply puts a message in front of my text everytime i chat. I need this so i can chat color. For example, if i press "t" to type, it opens chat, and once opened the color code should automatically be placed in. So lets say i wanted green to appear when i type. Then id need "&a" to appear in the chat box once i press "t."

If ANYONE CAN MAKE THIS ASAP ID BE VERY HAPPY!!!! IN RETURN I WILL GIVE A $10 DONATION RANK TO YOU ON MY SERVER : EcoCraft.McPro.Co

THANKS
