A list of managers, agents etc.

I'm making this list on my own, but I was wondering about a way to automate it, not only to create such a list, but also update it from time to time.

A software to gather basic data from IMDBPRO (movies or tv, limited by a country of origin, year, sorted by number of votes) with screenwriters, their managers and agents, directors and various kinds of producers and their contact info (if there is any) exported to a google docs spreadsheet.

Is there something like that? Would there be a demand for it?
