e-Mail adress check on internet

I have a list of email addresses. I must have checked whether these e-mail addresses can be found on the Internet, if they are found I need the link on which page they can be found. Example: anfrage at [login to view URL] - Link on: [login to view URL] If this email address cannot be found anywhere on the Internet, then the field must be filled with NULL. I will provide an Excel file with the email addresses. I would like to have a good and reasonable price for this work from you. I don't want to renegotiate anymore. Questions like sir, can you please give me more money I will not answer. The scope of the work is clearly defined. I will accept the offer where the price is cheap and where there are good reviews from other clients.
