Automatic Posting to Classifieds Site on Rentals Section

We need a Joomla/ASP component developed to take data from a MySQL database, format it and post it to a single city (of the user's choice) in the Craigslist network. Posting would consist of product information as well as a hyperlink back to the matching listing on the main site. Full automation is desired, but other solutions may be considered. Be creative! We just want a solution that will allow our customers to post their Property Rentals data from our database, in an easy way, to Craigslist without having to retype all the information into a Craigslist post. To post on Kijiji, Google Base, Vast, Oodle, MySpace, FaceBook and others classifieds site . Please submit samples of work that relate directly to this type of project.
