Terrific idea, Chef.
Without knowing the effort and the work that went into the event-planning, my comments may not be sufficiently apropos. Nonetheless, here it is. Not in any particular order.
1. Formalized event objectives (yes; more than just a "big" match for shooters)
- media exposure
- sponsors experience
- participant experience
- etc.
2. Event/strategic planning
- Timeline/gantt (announcements, hotel,stage-designs, ...)
- Resource requirement (stage-designs, props, volunteers)
- Ad hoc council? (industry players, PR firms,...)
