If you need for fast and qualitative web scraping, you are welcome. I use "Puppeteer", it is Google software, which let me proccessed any dificult use cases (infinite scroll, script injection in to target page, any use case witch you can do in common browser). I have own framework based on puppeteer, which let me complete scraping task more faster. I use nodejs(javascript) for scripting. I can build for you script for periodicaly starting and deploy it on you hosting. We can discuss output format of extracted data, for exaple csv, json or push to you url. If you have any questions I will very glad discuss it with you.
