Have you tried contacting an area radio/TV collector club?

I'd ask the nearest club for a recommendation. Even if they're not next door, they may know someone nearer to you. There might be someone out there, like a retired or semi-retired serviceman, who doesn't operate a full-fledged restoration business, but who wouldn't mind doing an odd job every now and then.
