Build a Harvester / Scraper to pull UK mobile & landline numbers from websites

I require a .exe program to scrape classified websites listed below. The data I am looking for are the phone numbers (UK mobile & landline). - I do not need the URL or details of the advert. I simply need a .CSV of the numbers. to be exported. - As with any scraper i should have the ability to control the speed of the harvest so I don't get blocked. - The .exe will run on a Windows XP machine - If there are search filters available then these should be available to be set in the scraper - I would require a program to search for numbers on the sites listed below at the same time. so they must be separate programs for each site or the program must be able to run at the same time scraping different sites. - the bid price must be for ALL 4 websites. note. remove the spaces in the url(s)! 1. adultwork. com 2. punternet. com 3. escortdirectory-uk .com 4. escort-england .com If there are any questions please contact me.
