Cost to have a 2332 GG1 restored?

Does anybody know how much to have a professional repaint done on a old lionel 2332 GG1? I can handle the mechnical aspects, but I do not have the means to properly restore the missing stripes and lettering. She runs well, but the only thing left are the keystones. I have heard that L&L screen printing do a wonderful job. Just curious on the cost. Thanks Mike
