Scrape 50K Australian Domains

I’m putting together a database of 50,000 Australia-based companies and need each record to include the company’s domain together with the current Managing Director or CEO’s full name. Please outline the sources and techniques you would rely on to reach both the volume and the accuracy I’m after...
