Good day,
I will gladly help you with your project. If I understand correctly, you want to scrape a site, get various details and save it to Google Drive. I have some questions/comments:
1. You mentioned "other sites also", I must implement the scraping for each website (the scrapping is not generic). So you have to tell me exactly which sites you want to scrap and what information you want from each site. My bid could vary on how many different websites you want support for.
2. Do you need the script in PHP or can I also use Python?
Once I finished the initial version, you can test it and I will make the required changes if needed. You can look at the code and ask me questions about it, so that you can understand it too. If you have any questions, do not hesitate to contact me.
Greetings
Matthias
