Email Extractor for craigslist and others

I would like a web based email extractor that works for: craigslist, backpage, kijiji and vast, etc. Should be able to pick which one to use each time. Also should be able to pick the category to search ( or select multiple categories ) and the geo location to search ( or select multiple locations ). I need to be able to specify the search terms to use for finding which posts to get the emails of. Also should have an "ignore terms" field to put negative keywords in. Should be able to save in a .csv file with the email and at least the subject of the post and the URL of the post. Should be able to save a project/campaign and be able to reload it anytime to redo the search. Each project should be able to also save multiple search's for use later. Should be able to schedule any project/campaign and choose which search or set of searches ( or all searches ) to run anytime ( cron job ). When you reload a job it should list the last run date, so if it ran via cron you know you can just download the .csv file and use it asap. Should be able to username/password protect the app, so a user has to login to use it. Not multiple user logins, but one username/password should be fine. Must be setup so it appears human and the sites do not block our program. Which may mean adding small delays to appear normal and of course make the app use a browser like look when getting the ads. I plan on setting this up for a couple users to use so this must be built in and dummy proof ( maybe adjustable within the app so I can adjust if need be ). Any questions, PM me. Will use GAF escrow only.
