Need to copy email addresses from a website

I would like to create a spreadsheet of email addresses for companies which are listed on the following website: https://suffolkshow.co.uk/tradestands/tradestand-information/2023-tradestands/

I would need their company name, email address and web address. Not every listing will have an email or web address which is OK, but where one is shown I would like it recorded.

We can supply a spreadsheet with all the company names in for you to fill in. There are approximately 600 companies listed.
