curl php craigslist

We want to have script created that logs into craigslist using curl/php - that allows us to populate a post up to the captcha field. We have listings that we want to post with all the fields stored in db - address, city, st, zip, description etc. We want to use curl to get all that prefilled out up to the point where the captcha field is displayed. Let us know if you need clarifying questions answered.
