Does anyone know a professional company that can do set ups for booths and cubicles for a 100+ vendor job fair

My company is hosting a job fair that will have 100+ vendors/companies coming to find applicants for their company. We need to have a professional company that can come in and set up booths and cubicles for each vendor. Does anyone know a company that can do this and who can quote me a price? I would great appreciate any kind of advice for the set up of this job fair because it will be our first job fair that we are hosting. Thanks!!
