Extract data from 400 emails containing leads

I am looking for some regular data extraction/data entry work

I have some emails sent which contain potential customers company name, email address and phone number.

I would like all the contact info (name, company name, phone number and email addresses) extracted and put onto a mega file.

Potentially could need you to do marketing emails to all these contacts once database is created. But for now I think 12 hours will cover the data extraction for the first list
