What are some business tours for a high school group, in southern california?

Alvin T: What are some business tours for a high school group, in southern california?
I need help with getting ideas of business tours in the LA area. It would be for a high school business organization, no more than a bus load of students. No specific type of businesses though, an example that we’ve done is LA Times tour.
Do you know if they already have business tours set and how should i request for one?
