74 DART REAR SEAT COVER

Anyone know who sells affordable rear seat covers? I have a 74 2-door dart s.e. and previous owner removed the cover and padding. Only thing left is the metal frame. Im looking to switch the color to white. and probably to the vinyl type of material. This is not a show car not looking to spend a ton on a legendary kit. Anyone have an rough idea on how much an uplostery shop would charge to cover it with there materials? Thanks
