My friends and I were thinking of hosting a small fundraising event with certain precautionary and sanitizing systems. We wanted to get ourselves a celebrity as well and approached several ones. We had to hire security for pickup, dropping off, and crowd control during the event. We started searching online for such security guard services and came across several websites. We have never hired such professionals before, and we need this event to be of absolute success with no problems whatsoever. Could someone help and advise me on what all to look out for when hiring such services online?
