What equipment would I need to start creating model spacecraft from broken toys?

I would like to start making model spacecraft (Sci-fi not replica) from broken toys and other plastics. What equipment / reference would I need to do this? I.E:
. Something to cut the delicate plastic without breaking it
. Sites where I could acquire broken or disused toys
. Techniques and Tips Videos on 'Youtube'
. Paints and where to get them
I'm not sure what this hobby is called although I figured maybe 'prop-art' but I haven't found any reliable sources of information yet.
