Craigslist Email Promoter (1267454)

I need a Craigslist Email extractor plus email combo program made that will auto search [login to view URL] in any category and location that I specify on any keyword in the description and/or title on a continual basis. It will constantly run in the background and search for postings to add to the queue and then send only one predetermined (but editable) email marketing message to the one who made that post using ones own smtp server and authenticated email login like Outlook allows.
