Email Finder

I have 25,000 records in excel.

Each record has a generic email addresses e.g. ---------- and three names e.g. Dave Smith, Rob Thomas, Peter James.

I need the correct email address to be found for each of Dave Smith, Rob Thomas, Peter James.

I understand this can be done using email finder tools e.g. Hunter ( ---------- ).

Please can you let me know if you can do this for 75,000 records (25,000 x 3).

I would like it started immediately and completed within 5 days.

Please can you let me know if this is possible?

Thanks
Matt
