Hello,
I've read the requirements of your Automation project and would like to work on it. I've over 4 years of experience in Web Scrapping and Automation using various technologies (.NET, Python, Selenium, iMacros, PhantomJS, CasperJS, etc.)
I'd suggest you to use iMacros scripting for this automation project. The output script will be fast and accurate. Plus, it will work nicely on Windows and Linux both.
If you want this developed in any other language, I'd suggest Python or C# with Selenium.
I'd strongly suggest you to go with iMacros though. Let's discuss all the requirements in detail and once everything is finalized, I'll start working on it immediately.
Looking forward to hearing from you.
Thanks.
