Craigslist search tool

Looking for someone to design a comprehensive search tool for finding specific items posted on craigslist nationwide without having to go city by city. This program is for my personal use only and is not to be resold or marketed. There are a couple of tools out there but not one that fits my specific needs. I have an old program that no longer works in its current form and could be given to the developer to tweak as needed. Please contact for more info. I am open to discussing a number of options regarding cost, set up, maintenance, etc. Thanks!
