I need someone to export email addresses and save in CSV format

General information for the business: We sell services
Description of requirements/functionality: I have around 70k emails stored in webmail (around half will be duplicates). These emails can be read using the following applications:

- horde
- roundcube
- squirrelmail

You can also access via imap.

I need someone to do the following:

Each email contains the following information:

- Name
- Job Title
- Email
- Phone Number

I need someone to extract this information from each email (there are about 35k emails) and save in CSV file.

The CSV file is then going to be uploaded to mailchimp so needs to be in the correct format.
