Alerts for professional sports tickets

I'm the founder of Ticketlab, here to answer any questions you might have! Want to get notified anytime courtside Lakers tickets cost $200 or less? Trying to get Blackhawks tickets for under $50? Setup a notification and we'll search every day and let you know when we find your tickets.
I'd love to have an alert by team and geography - i.e. when are the Cubs in SF or Oakland? Honestly, I'd actually love to have that for multiple teams I'm interested in - Cubs, Sox, Bulls, Illini, etc. for SF and Oakland (but not, say, San Jose).
