There is a bookstore in California, near San Francisco, that is pure ESL. It is a small retail location but has a great website and catalog. They specialize entirely in ESL books and materials. I always get ideas just looking through their online catalog.
I highly recommend it!! They also give wonderful free workshops (if you happen to be in northern California!)
Here is the contact information.
Hope that helps!
