how to put into catagories

I am liquadating a hot wheels and other die cast 1/18 collection, consisting of over 10,000 pieces , all in original packages.  Does anybody have a suggestion as to how to organize them, or put in different catagories?  The packages range from 2 to a package to 20 cars to a package.  Also, different manufacturere..  There are 44 tupperware 18 gallon containers!!!!
