Re-finishing Arne Jacobsen series 7 Ant chairs/  

Hi folks; enjoying-- this site. I have two Arne Jacobsen 1957 series 7 molded plywood chairs; they are NOT ash wood...but regular wood, in WHITE: WHERE can I send them to get correctly -re-finished without costing $500 each? The finish is slightly gloss...not even semi gloss, but like a rilsan finish...no wood grain showing, they have cracked on the seat. Any professional place nr NYC? I'd even send them long distance to find someone who knows what finish is correct. Thx in advance..also, I cannot post pics don't have them as 'web-sites.!
