I found someone in Belgium selling Giant Propel decals. You may find similar for yourself. Then hand them to the repair person for the paint work.
FWIW, unless a frame is valued over $3k or so......I wouldn't blow too too much money on a fancy new paint job for a carbon repaired frame. I'd try to find the decal online and get them to paint the chainstay original.
You'll never overcome that valuation hit from the crash and repair. Despite most repairs being stronger than original since they don't sacrifice strength for weight.
