I use python language.
My scripts works on windows, mac or linux, but linux is preferably. I can schedule scripts on server if it is required.
I have more 100 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, 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 captha on site in avtomatic or manual mode.
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.
