Whether to manage the event in-house or employ professionals?
This is a very important decision. If you have the key resources in-house (experience and time are probably the most vital) then managing it yourselves may be an option. However, if these resources are not available then we would strongly recommend you use professionals experienced in organising the required type of event. Events organising can be much more complicated than it at first appears and the assistance of outside experts gives access to experience, time and knowledge that is likely to be invaluable.
