I use python language and scrapy framework. My scripts works on windows, mac or linux, but linux is preferably.
I have more 300 finished projects (google scraping, facebook scraping, yellow pages, linkedinIn, amazon, webshops and other sites with lists of any items).
I can scrape secured and protected sites, ii site block IP i can use proxy or TOR, also i can try avoid captcha.
I can export data into json, xml, csv (excel), or any database (mysql, mongodb, mssql, etc).
I can develop web-interface for management running script (start, stop, etc), using PHP, HTML, JS.
