Craigslist Contacting Service for a Specific Item - Send Emails daily to sellers

Hi I need emails sent daily to sellers of a specific product.. There are about 50 listed per day in most of the top cities.. I would like to start with 1 city this week to see how it goes and then possible start doing the top 50. I will provide you with the craigslist search and email that needs to be sent to the sellers. Send me a quote per email sent.
