I would've kept sharing information, and also trying to figure out how to co-mission so some of my other projects benefit from this guy's passion. I'm an educator by trade, so I guess I don't mind sharing what I know, provided it's not a huge burden. It sounds like you work at the guitar center (is that right?), if so, there might be more boundaries than I have as just a guy with an opinion. Even if someone couldn't play, I'd try to boost attendance by getting him to attend one of my kid jazz band performances. Let him know that if he can meet certain requirements, he could join us eventually.
I remember one guy who spent a lot of time educating me on basses when I was new at Long and McQuade in Toronto, Canada. He showed me how to get a Jaco sound out of a bass and I was deeply appreciative. I still remember the guy 30 years later. And he helped fuel my passion.
You never know when you're planting a seed that eventually becomes a mighty oak tree.
