Does anyone know where for a Toyota celica?

Where I can get a custom seat cover for the back seats 1992 Toyota celica if it makes a difference? For Christmas im getting my husband racing seats but he wants the back with like a black leather so I wanted to get our last name and the old school celiac sign on it.. Im looking to get it under 50 or 50 exactly. Does anyone have any ideas on where I can get it. AutoZone and pepboys already told me they have no way to get it nor know where to begin to look for custom like that.
