Crawler to obtain emails

Natura and Avon are two big companies that manufacture beauty products. I would like to have the emails of their sales representatives. Both lists are accessible via their websites by imputing a postal code and a captcha. Natura's "find your representative" website is here: [login to view URL];MenuItem=22 Avon's "find your representative" website is here: [login to view URL] The deliverable is a .xls or .csv with names, emails and phone numbers of representatives. My expectations are at least 500.000 emails for Natura and 200.000 for Avon.
