Curl/PHP login for Craigslist

We need the following: A script written in PHP/Curl that draws an account from a flat file or database and logs into craigslist. Example, a user will push a button on a page, and an account will be selected from the database and logged into craigslist, all invisible to the button pusher. The script must be UNENCRYPTED. We will not accept any encrypted scripts. Will pay $50 for this simple script. DO NOT APPLY if u have no rep DO NOT APPLY if u expect to be paid prior to our inspection of the final product. WE WILL NOT RELEASE ANY FUNDS TO YOU UNTIL SUCH TIME SCRIPT IS OPERATIONAL AND CONFIRMED WORKING ON OUR SERVERS. NOT NEGOTIABLE!
