Craigslist - make postings and/or extract email addresses

Are you an expert on ANY aspect of Craigslist? My interests are two fold: I. I am looking for an automated way to extract email adresses based upon gepgraphy, category etc. Either (i) you can do this for me routinely, or (ii) you can write a program that does this for me. Or (iii) you can sell me a program that does this automatically. II. I am looking for you to post my posting on Craigslist. The postings must be made in the catgories/geographies of my choice, and should NOT BE FLAGGED. Thank you.
