Hello Sr.
I'm Jorge from Argentina, a responsible person who have wide experience working with Web Data Extraction (Scraping) projects as you can read in my Portfolio.
Would be nice to get in touch to know more in deep the scope of the project. I did before different scrapers (Windows based), using .NET C# and/or WinAutomation Scripts (both Windows compatible and free to run them). Message me to understand your requirements.
Thousands of projects done succesfully at the moment (within this platform and outside it), with different websites challenges (captcha security, javascript, ajax, flash, use of Proxies). Also, with a wide variety of amount of data collected. Since few records to millions. Also, if the job is an on going one, I usually save the scripts to run them in the future (this reduces the time, and probably the quote).
I'm interested to help you on this specific scope you have in mind, may we could discuss further and agree the workflow to receive the data/script/program you are looking for, the estimated time and quote.
Finally, I'll invite you to visit my Portfolio, here, to know me more in deep and see what people says about my jobs. This is the link: https://www.freelancer.com/u/PigtailXL.html
No more Sr., don't hesitate to contact me, I'll be glad to answer you.
Have a nice time.
Regards.
Jorge.
P.S.: I will not accept any previous award, before to discuss with you all the details.
