Power Button Cover Lost

Would anyone know where I could find a replacement for the top power button cover, its a red one but im not to picky, I just need to get it back to the customer asap, the only solution I have found its to buy a broken one and to take the power button cover off, I have found some from china but the time of it getting here is like a month or more. I cant seem to find a place state side that would just sell that part.
