I need a sales spreadsheet of 500 England based law firms

I need you to create and produce a spreadsheet for me which will contain 500 law firms. The law firms must have an office in England and their revenue has to be over twenty million pounds.
For each law firm you list, I need you to then find 4 contacts within the company who are in leadership roles.
The roles I need are;
CMO, Head Of Marketing, Marketing Director, Head of Diversity Equity & Inclusion Director, Diversity Equity & Inclusion, Director of Strategic Business Development, Head of Partnerships



If you cannot find the roles above, I will accept the roles of; CEO, Vice President, Senior Communications Manager, Chief Financial Officer, Head Of Finance
