Accurate Web Contact Data Extraction

I have a list of online sources where I need all available contact details—names, roles, emails, phone numbers, and any publicly listed social links—pulled into a single, well-structured Excel file. Many of these sites use pagination, dynamic loading, or the occasional bot check, so the solution has to be resilient (Python + BeautifulSoup, Scrapy, or Selenium generally work best in my experience, but I’m open to whatever stack you prefer).

Here’s what I expect:
• A repeatable script or crawler that targets the specified URLs and captures every relevant field.
• Cleaning and de-duplication before delivery so the spreadsheet is ready for immediate use.
• An Excel workbook with separate tabs if multiple sites need to stay segmented, otherwise one master sheet is fine.
• Clear documentation or inline comments so I can rerun the scraper later should the sites update.

When you reply, please include:
– One or two similar scraping projects you’ve completed.
– The primary libraries or tools you intend to use.
– An estimated turnaround time once I supply the final URL list.
– Your price for the initial run plus any cost if periodic refreshes are required.

Data accuracy and confidentiality are essential, and I’m happy to set up milestones to review samples before the full export. Looking forward to working with someone who can get this done quickly and precisely.
