Looking for Tickets to Classical Concerts (Seung-Jin Cho, Yuja Wang)

Not sure if this kind of post is allowed or if it'll reach the right audience, but figured I'd try. Anyone here have or know people who have tickets to performances by either or both of the pianists above that might be looking to sell them? Cho is scheduled to perform on November 12, Wang I think is May 8; both at the Chan Centre.

Alternatively, are there any places I should be looking for ticket reselling in Vancouver? I've tried some basic searching on Google and Craigslist but haven't come up with anything yet. Thanks for any help with this.
