Craigslist poster

Hello, I need someone who can send emails to 600 people (successfully emailed)on craigslist who post. The emails will be in "vacation rentals" category city will be provided. The pay for this job is $30 for 600 emails. We will create an email account in gmail and provide the login so email will be sent through that account. Also craigslist blocks email addresses that forward to too many craigslist emails at once so this has to be done in a way that we dont get blocked. If the right person is found this can be done on a weekly basis if the conversion is right. We are offering a free service so my goal is that out of 100 emails at least 2 should signup. Payment will be through paypal after job is complete.
