There are many elements of a successful trade show-signage, broshures, handouts, apparel.  To have a successful show, use the following check list for them.

Signage-- Visible for at least 20-25 feet and attractively done. 
Brochues-- Short concise statements about what you have to offer
Imprinted Items-- Useful, often inexpensive items that help people remeber who you are and what you do.
Apparel-- Setting appropriate apparel that shows your professionalism

These and many more are issues we can help you resolve.  Call 804-515-0300 or email at matt@logomd.com
