CRAIGSLIST EMAILER

We need a craigslist cron/timer job done in either php or asp.net to fetch list of emails and auto reply to them. The database you create will need to list the location and category so we can add locations and categories in the future. For example : [login to view URL] orlando is a city that needs to be saved in the DB along with other cities we want, so that the cron goes through all the cities and crawls each city. "web" is one of the categories we want, this needs to be stored in the DB so that we can add more categories using php my admin or sql management studio
