I'm web scraping expert. I provide leads for all types of industries/verticals in many countries, including e-commerce. All leads are Optin and TCPA Compliant unless only data is required and not optin. I use python scrapy framework. My scripts can run on linux or Windows. I schedule scripts on server if it is required. I do google scraping, facebook scraping, yellow pages, linkedin, amazon, webshops, specialty sites and other sites with lists of any items. I can scrape secured and protected sites, my crawlers can enter into login form, emulate ajax requests etc. If site block IP I can use proxy or TOR. I can try avoid captcha on site in automatic or manual mode.
