I need a clean, well-structured CSV that lists every interior design business you can find in Mumbai, Pune, Nashik, and Surat. Your sources should be Google Maps plus the listings on Justdial and Yellow Pages. For each company, capture exactly three fields—business name, full address, and phone number—keeping the phone exactly “as listed” on the source page (no re-formatting into international or local styles). I do not mind which stack you prefer—Python with Scrapy or BeautifulSoup, browser automation with Selenium, or a different approach—so long as the final spreadsheet is comprehensive, de-duplicated across the three sources, and ready for me to open in Excel without further cleaning. Before delivery, please spot-check for obvious errors (e.g., mismatched phone numbers, partial addresses) and remove duplicates where the same firm appears on multiple sites.
