Dear Client,
I have read your description carefully, and finally I think I will be good candidate for your project.
Throughout these years, I have gained abundant experience with scraping using scrapy, selenium web driver, puppeteer, beautifulsoup and so on.
And also have skilled in Multi-threaded scraping, bypassing captchas, using PROXY/VPN to rotate IP.
If everything is impossible, I will create real bot which uses real web browser(not test web browser).
Anyway, please share url, at that moment, we can determine difficulty of this work.
Thanks
