A: If you go to HomeAdvisor you can go to their contractor directory, that is what we scrape from. You need to give the program the url for the page of listings you want to scrape. You will need special proxies, which is talked about on the ReadMe page and companies I have used are recommended.

How you use the data is entirely up to you, some build more dirty type sites that are more niche and some try to reach out to the businesses to sell them services.
