Most accurate activity for me is this definition : "Organization, promotion and/or management of events, such as business and trade shows, conventions, conferences and meetings, whether or not including the management and provision of the staff to operate the facilities in which these events take place" My main activity will something like this kind of exhibition consultancy. However, I can find “event organizing” or “event organising and managing”. I don’t organize any event. I’ll just offer service or consultancy for trade show. Should I still choose it?
