Trade Show Development Trade shows can be expensive. By the time companies rent trade show space, booth rental/purchase, collateral materials, pre- and post-show mailings, can easily exceed $15,000 for even a midsized show. Despite making this kind of investment, up to 80% of companies fail to follow up on leads taken at a trade show. Avoid this kind of waste! The Marketing Department will help you keep your budget realistic and will help you have a successful show. Following a trade show, a plan will help you make the time leading up to and after the show very successful. See testimonial area.
