Or.. maybe you could talk with the Master Gardeners and see if you could collectivly hold a hands on workshop on how to start gardening. Master Gardeners LOVE to share their knowledge, and their services are free. They may just need a spark of an idea.
Also google "Plant a Row" and see what you find. It is a program started by the Garden Writers Association in an effort to get people to plant extra... just like you are doing.
I wish you the best of success with your endeavor.
