Cleaning 2 files (1 million) and (235k) of french speaking emails addresses

Hi, We need to find the best freelancer that is able to very clean 2 files (1 million) and (235k) of french speaking emails. We begin to ask around $600. You will have to ping, or send test emails to the 1 million addresses at a time to identify the valid/ invalid email addresses, to delete all bounces, spam trap and all wrong emails. In your answer, you will give us your best timeline. Be careful : Most service providers in our list of email limit the number of validation requests per IP address in a specific time periods (usually an hour), so a solution that works would need to use some sort of rotating IP solution or another way to use multiple IP addresses. In the file we will include known email addresses to check the quality of the work done. If the match rate is less than 80% no payment will be made. If you are interested, we can supply a test file with 10,000 addresses to assess your quality of future work.
