I would recommend checking out
www.teamsets4u.com They have thousands of team sets. Here is a link to their Cubs team sets.

The owner of the site is a member here and really nice guy. You could probably pm him through the site and work out a better price if you are buying several team sets. Hope this helps.
PS: I am not affiliated with this site in any way, just looking to connect a couple of board members together. Good luck!
