Create craigslist campaign system

I need you to develop some software for me. I would like this software to be developed for Windows.I need someone that can create or has an autoposter that post on craigslist automatically. It needs to be able to post an unlimited amount of ads on craigslist as well as post in all cities. Keep in mind this auto poster must be able to get past craigslist security and have ads go live. If you have never created a system like this please do not bid. Also please understand we are looking to build a long term relationship with programmer of this system because it will need to be updated per upgrade securtiy settings by craigslist.
