Will build web scrapers in python / scrapy framework. For last 5 years, we built tens of web scrapers for many websites(for ex: Shopping Sites - Amazon.com, Ebay, Targat.com Wlmart.com, Blog sites, etc). Used various techniques to avoid being blocked from websites. We can not only build and provide data scraper, but also will update scrapers according to website changes(change of contents and html layouts).
