Data Downloading Application

We need a program that will go on the website [login to view URL] and look at every ad, in every US city, in each job category, and download the text in each ad. The program will sort out and delete all: Phone numbers email addresses websites links html at all The program will store all of that data in an xml file on the hard drive. (using a simple syntax we will discuss) This program will need the ability to run continuesly 24/7 around the clock without any human interaction. And this program must be 100% error and bug free. This program will also need to handle internet disconnections. The computer this program will run on disconnects and reconnects to the internet quite frequently, so, this program will need to recognize that the internet connection is not present and try again until it detects the internet again and pickup where is left off. This program will not be posting any ads, it will simply be grabing the informaiton inside of all ads and storing the text. The program will need to update the xml file every 6 hours with the new it has downloaded. Please PM any questions. Budget $150
