Personally, I would not rely on the skills of a 'good beginner' to teach someone to fly.
If we were talking about a traditional 5 pound .46 engine glow-fuel trainer, I'd agree absolutely. But I think a "good beginner" might be OK (safe) for the plane we're talking about. Given the shop owner's motivation, I think he would not be asking if he didn't think he was qualified to teach on that particular plane.
