We are a homeschool support group with about 150 families. We are planning an expo and would like to invite museums, book stores, dance schools, and the like to set up tables and display what classes, discounts, and materials they have available for homeschoolers. I'm in charge of finding a few vendors, what is the proper or most successful way of soliciting support for our convention? I am new at this, and would appreciate advice from some pros. Thanks
