Craigslist data entry, replying to posts

I'm looking for a company who specialize in replying to craigslist posts, I can supply a list or provide the tool to gather posts to reply to... Things you will need to do - entrer capachia - reply to post with provided template text, making a slight adjustment each time - record the urls once submitted I think there is a sending limit replying to posts each day of 20 via craigslist? so you would need to rotate your IP Address etc.... we'll do about 500 for a trial to see how things do and I am looking about 4cents per reply sent successfully and we'll negotiate a rate when I up the amount of posts that are replied to daily
