There are 2 options available to you. First, contact the show organizer to find out who has been selected as the Official Service Contractor. This contractor is a primary source for information about planning for an exhibit in the United States. In addition to managing the logistics of the show and supervising many of the labor groups working on the event, the Official Service Contractor can also provide rental booths that can be customized to your needs.
Another option is to hire an Exhibitor Appointed Contractor (EAC). EACs offer the opportunity of managing your show experience at your direction. EACs not only can provide the labor to install and dismantle your booth and managing communication with the service suppliers to the show, some organizations can also design a booth to meet your particular needs.
