Data scraping of property sites

Data scrapper/extractor which can convert the data and import it into website manually. I would like to extract property listings from other property websites, and import them into my website, BUT, the user name and password has to be extracted registered in our website by inserting details. This project involves scraping several websites to compile a database of contacts. The contact details should include all available contact data that can be obtained from the websites such as “Contact Name”, “Title”, “Areas of Specialty / Services Provided”, “Business Name”, “Address”, “Phone”, “Fax”, “e-mail”, etc and property details with pictures... so on. After scraping the data, I will manually select which properties has to be posted based on criteria like , listing posted individually and listings with photos, listings of properties posted by agent with photos, listings based on some areas etc. After selecting the listings they have to be posted to my site. Check how you will work with registration process in my site [login to view URL] and posting of the property in my site. This is continuous process whenevr I want and there shouldn't be duplicate of data. I would like so do process manually as well to make work easier I need a robust and reliable script which will scrape information from the following property sites : [login to view URL], [login to view URL] [login to view URL] [login to view URL]
