Already worked with similar projects (http://www.freelancer.com/projects/533322.html), (http://www.freelancer.com/projects/PHP-Linux/linux-craigslist-crawler-scraper.html). Very interested in this project. Ready to start immediately and develop solution using PHP with CURL Async I/O to post several ads simultaneously. Script will have support for proxies and different IPs. Captchas can be solved using well known Decaptcher API. Script can run manually or as a cron job. Please contact in PMB for details.
Best Regards,
