Program to search for emails from specific websites

Here is the program that needs to be built: The user will import an excel spreadsheet with hundreds of domain names in column A. The program will then search for multiple email addresses within the domain only. Once it has finished it will then check the email addresses and ensure that the extension of the email addresses match the original domain name and auto delete any that do not match. The program will then out put all the information in a spreadsheet as follows: Column A Line 1 - Domain name(1) Column B Line 1 - email address(1) Column C Line 1 - email address (2) Column A Line 2 - Domain Name (2) Column B Line 2 - email address(1) etc etc I will choose someone within the next 3 hours and you must be able to start immediately!!
