Justdial & Sulekha Full Scrape

I need a robust scraping solution that can harvest every publicly available field from both Justdial and Sulekha. That means the script should capture all listing information—business name, contact details, address, website, ratings, reviews, categories, photos or any other data point that appears on each profile—across every category offered on the two platforms.

What I expect from you:
• A repeatable script (Python preferred, but I’m open to alternatives) that I can run on my side without hitting platform rate limits or getting blocked.
• A clean, de-duplicated data set delivered in CSV or Excel.
• Brief documentation so I understand how to configure location, date ranges or other parameters before each run.

Please ensure the code respects robots.txt where required and handles captcha or anti-scraping countermeasures gracefully. Let me know your approach and estimated turnaround; I’m ready to start right away.
