I need ideas for a English project?

I am doing a Renaissance project for my cl. My subject is Caravaggio, Michelangelo Merisi da-the famous italian painter. I have to do a 3D exhibit that is like a museum about him. The size of the project is about 24x12x12-a typical box. We are not allowed to use pictures off the internet-any suggestions for a different way to get the pictures? Also, any suggestions for other things to use to signify his life or his work? Please keep in mind that buying a lot of materials is not good.
