Question about advertising?

[Shani]

the highest paid actress in advertising was brittany spears with pepsi, she got paid about a million us dollars for her thirty second commercial in the nineties.

these days it would probably be about, half that, probably even less at about twenty five million - depending on who and what movies they were in at the time. if they are desperate for exposure it will be a cheaper gig.

research flights to Philadelphia if you need people to be flown there, costs of camera's, lights and electricity. will they need accommodation? all of this is a cost.

to make the add, is new technology a cost? do you need to buy a HD editing software etc?
i hope this helps kick start the ideas
