Rick's right...
But as an addendum... if the project's budget doesn't allow footage from istockphoto, you may be in for a hard search. Their stuff is typically dirt cheap... usually much less than other stock sources. I'm not sure if I've ever heard of any high-quality footage sources that are less expensive than iStock.
