Potential sponsor list needed

Hello!

I'm looking for sponsorship for my next event, and I need the names and email addresses of 50 potential sponsors.

They all need to be either marketing directors or senior leadership, and operate on the film services side of the film industry in the UK. Ie - they need to be UK-based companies that assist in making films, as opposed to studios, production companies or distributors. Think VFX houses, financiers, equipment rental, insurance companies etc, rather than the likes of Disney, Blumhouse or Signature Entertainment.

If possible, it would be great to pre-approve the list of companies you find BEFORE you start finding the people that work there and their contact details

Please do ask if you have any questions!
