Scraping email addresses from websites

I am running a seminar for estate agents in Cape Town next month and urgently need to discover the email address of say 2000+ residential real estate agents (sales not rentals) in the Western Cape area of South Africa, including Cape Town and its suburbs and all towns within a radius of 50 miles (inc eg Somerset West and Wellington). We do NOT need Pam Golding agents or Rawson agents.

Agents might be called sales associates, interns, managers, team leaders, negotiator, agents, etc.
A starting point to find agents might be https://www.property24.com/estate-agencies/western-cape/9 Click on the agent’s logo although beware that this might show areas outside the Western Cape area too. You can reveal the email in the right hand box, but this is quite manual. It is usually best to go directly to the company website where email addresses are often displayed eg https://www.remax.co.za/real-estate-agents/south-africa/western-cape/ but make sure you always select Western Cape.

Entries should be entered into an excel spreadsheet under the following headings:

First Name Surname Email address Company Town/Suburb
