How to define a project? A few key points:
Type of the event: professional, private or public, big or small, inside or outside?
The choice of the date is an important factor of success. The schedules?
The location, the hall? The good choice, the appropriate size, matching the program.
The aim of the event? For whom, for what?
Regarding prices, it’s difficult to indicate average amounts because of the huge differences between events.
The program, the artists, musicians, DJ and other participants.
Activities you would like to propose. Are they appropriate for the target public?
The organization, the resources, the choice of the services you need.
Advice, coordination, project manager, planning.
Communication is really important in case of a public event.
Regulations, security, permissions, sound level limitations.
Logistics, transportation, installation, setup and takedown.
Entertainment, hosting, atmosphere, motivation, energy.
