20k Business Contacts Scraping 12h

I have a business directory site that lists the exact mailing addresses I need. Your task is to scrape 20,000 complete records—only contact information, and specifically the mailing addresses—for the businesses shown there.

Here is the scope in plain terms:
• Extract every available address field (street, city, state/province, postal code, country if present).
• Organise the data in a clean, comma-separated CSV with consistent column headers.
• Validate that the final count reaches 20,000 unique records; no duplicates.

Timing & payment
I’m paying a flat $20 and I need the finished CSV back within 12 hours of project acceptance, so please only respond if you already have the tools and experience to hit that deadline.

Acceptance criteria
• 20,000 unique mailing address rows delivered on time.
• Data matches what appears on the live business directory site.
• File opens without errors in Excel or Google Sheets.

If you’re confident you can meet the volume and the 12-hour turnaround, let’s get started right away.
