Negative Review Extractor

I'm looking for an experienced freelancer who can extract business data (including emails) from Google Maps or similar platforms, ideally in an automated way.

The focus is on local businesses with poor Google reviews (1–3 stars). The data will be used for B2B cold email outreach (fully GDPR-compliant, no spam).

Target industries (examples):
• Dentists, lawyers, car dealers, restaurants, craftsmen, beauty salons
• Germany-focused

Required data fields:
• Business name
• Google rating (stars + number of reviews)
• Address
• Website
• Email address (from website/imprint)

Important:
• Only business contacts, no private individuals
• All emails must be publicly available and compliant with GDPR
• Final format: Excel or CSV
• Target volume: 5,000–10,000 clean and usable contacts

Bonus if you use tools like Outscraper, PhantomBuster or your own scripts.

Please include:
• Your method & tools
• Delivery timeline
• Your price per 1,000 valid records

Looking forward to working with you!
