B2B lead list: 20 logistics companies in Lubuskie, Poland (Sample work)

Sample work on real public company data, not client work. I built a list of 20 transport and logistics companies from 11 towns in Lubuskie, Poland (incl. Kunowice in gm. Słubice): name, type (HQ or branch), website, generic company e-mail and phone, NIP, city, notes, source URL and check date. Every field was checked on the official website on 2026-10-14, and all 16 listed NIP numbers pass the checksum. No personal contacts; a blank cell means the company does not publish that data.
