Hello,
I am interested in your offer. I am a Python programmer and thus have the most experience in scraping using this language, however I have also written scrappers in NodeJS or plain JS. I am confident I can complete your project, however I cannot say how long precisely it will take considering the unknown nature of the data. All in all, I can assure it won't be long. Please contact me over PM with more info about the data, in case of any questions or to discuss the details.
Kind regards,
Wiktor
