Web Srcapping Bot - repost

We have one web tool requirement, we need to grab as MANY RECORDS AS POSSIBLE within certain parent categories. The tools should collect website names(domain) from search engines (google,bing etc.) using particular key words, also able to fetch the external links from any website and store website links in relevant category. The tool also needs to scrape data from each domain (like contact address, email, website title, meta description, social profile links, server location) & also able to generate thumbnails. Required two types of tool in one script 1. Only gather domain names 2. Using domain list scrap data from each website. Only confident & experts apply. Thanks
