Find the contact email addresses for x 250 websites using Google

The task is to search Google UK (UK is very important!) for the following search terms....

designer radiators
heated towel rails
electric towel rails
electric radiators
thermostatic heating elements

You are looking for the contact email address of the top 50 websites under each search term. If no contact email can be found, move on to the next website in the list until you reach 50 per search term. Provide all the email addresses in an excel spread sheet. You will likely find DUPLICATE emails across multiple search terms. Please DELETE these duplicates and carry on down the google lists under the search terms until you have 250 UNIQUE email addresses and website contact details.

A random check of 10% of the list will be undertaken to confirm the addresses are accurate and exist. The task will only be considered successful if all the email addresses are found to be correct and the websites found.

I hope I have described this task clearly enough here, but please ask me any questions if anything at all is unclear.

Thank you for reading this.

Best Regards
