Portlights / Portholes

Need some intel on portlights. My wife and I just purchased a 1992 Island Packet 44 which is undergoing an extensive refit at Macks Yacht Services. The 16 portlights are fogged and the glass needs to be replaced. I am hoping that someone may have a source that I can send the "lid" i.e. closing frame and glass  and have them repaired or better a source that I can purchase new lids to fit my current porthole. I have seen a lot of DYI on this site and others but if possible I would rather send them off to be fixed. I can't imagine that I am the only one with this issue any ideas would be appreciated. Thanks! Rob
