A scam? Wow, now I really want to hear more about them! Can think of a bazillion more lucrative scams to run other than a tube rebuilder LOL
Not only do they claim to offer rebuilding services but also rebulding gear and training.

I get the impression that their business is mostly centered around the notion of selling rebuilding equipment to foreign countries (where labor is cheap and CRTs still reign supreme). The other potentially much more profitable scheme would be to help municipalities in their "recyling" (AKA disposal) of CRTs.
