Data Collecting / Classifying

I need a freelancer to collect *very* specific e-mail addresses from certain types of companies. Each e-mail address must be correctly marked according to some parameters. I'll provide an Excel spreadsheet and I'll --pay per contact-- you collect. I estimate this project will involve between 2500 and 5000 contacts, but if I'm happy with the result, there will be a lot more. I want *no* duplicate or invalid e-mails. The information I need is: - Company name - E-mail address (mutiple addresses per company are accepted) - Classification of this e-mail on several categories. This is made simply by writing '1' in the appropriate column(s). Most e-mails need only to be marked on 1-3 categories. I'm willing to make a few payments as I see the results. If both of us are happy, we will continue. I will mention the type of companies I'm looking for to the interested, as well as how to find the appropriate websites. I *will* make random checks on the e-mail to verify if they are valid and correctly marked. Only occasional mistakes are tolerated. Example of the Excel spreadsheet is attached.
