Patriciag-
As your profile indicates you are in Los Angeles, why not give Pasquini a try? Pasquini Espresso Co - 213-739-0480, they are on Olympic Blvd or check out their website
http://www.pasquini.com
Although I have never called them or used them for any repair services so I can't vouch for them, Pasquini at one time rebranded Olympia products (Pasquini Livietta = Olympia Coffex or Maximatic). I'm not sure if Pasquini ever rebranded the Cremina.
You might want to give them a call and see if they can either do the refurb for you or refer you to a local craftsman that can do it as at least they are in Los Angeles.
Others here may be able to tell us about Pasquini's services - maybe Marshall?
