I am looking to obtain building, or rooftop outlines shapefiles for major cities in California. I have looked around but there does not seem to be a cheap agency that has these.

Can anyone offer some advice on where I should continue my search, or can provide what I am looking for?
Any advice would be highly appreciated.
