I think you've found the right person, but you can't speak to folks in your home town before level 20 -- it could be level 18, but I'm not sure. At 15, you're still too young either way. Once you level up a bit, you can chat with him and get the expected response.
Edit to clarify: Clearly, I mean you can talk to the Wayfarer's Brotherhood person only after you reach a certain level. You can talk to other folks in your home town at any level, of course. :)
