Things to take into consideration:
Rental of studio per hour or daily rates
hiring lighting manager and assistants daily rates
hiring production manager and assistants daily rates
hiring director daily rates
paying for genius to set up
paying per hour for that person's time
paying for certain equipment used
paying cameramen (probably used 4 here) daily rates x4
paying or food for entirecrew at any breakfast, lunch, dinner breaks
paying for the announcer (voice over)
paying for audio studio for announcer
paying audio engineer
POST production
paying for editing suite (eh, typically $500- $750 per hour depending on city and what is available in the studio)
paying for editing
paying for outside creative sources
I could go on and on but I'm stopping there....just a general idea
