Research 10,000 German Companies for Charity Sponsorship Leads

We are a human rights charity seeking a researcher to build a list of 10,000 potential corporate sponsorship prospects based in Germany within 3–5 weeks. For each lead, provide company name, contact first and last name, job title, full company address, landline phone, business email, mobile number, company and professional social media links, and source URLs for verification. Use publicly available business information; leave unavailable fields blank and do not guess. Deliver an Excel or CSV file with one row per company and avoid duplicates. Milestones: (1) submit 20–30 sample leads for quality review; (2) deliver the first 1,000 approved leads; (3) deliver the remaining verified leads in agreed batches to reach 10,000. Include your research method, expected completeness, and delivery schedule in your proposal. Fixed project budget: US$250 maximum.
