I don't know if there's a conservatoire or opera-house nearby. Even classical can help since after all what matters is voice control. And after all opera singer learn power, control and repeatability without having voice problems.

Any solution enabling him to overcome the wall he'll soon meet working on his own, again if he doesn't have classes already.

I guess it's the right time since he's been serious enough to get there and everyone get more and more pro.
Yeah, he's already taking classes. It's been immensely helpful, mostly because on the last EP he sung more with his throat (newbie mistake) but now he uses his entire body. With even more lessons he will hopefully become really good at the technical aspects of singing soon enough.
