Sanitized USA Marketing Leads

I need fresh, accurate contact lists of decision makers at marketing agencies and related contractors across the United States. For every city you work on—starting with New York, Los Angeles, Chicago, and Dallas—I’m expecting between 1,400 and 2,000 leads. Ultimately the project will cover 50-plus cities, so capacity to scale is important. What matters most is quality. Every record must: • Belong to a CEO/Founder or a Marketing Director (Sales Managers are useful but not required) • Contain a direct, non–catch-all email that has been fully sanitized and verified to keep the overall bounce rate below 1% • Be unique—no duplicates within or across cities You’re free to employ any combination of Apify, Python scrapers, AI enrichment, or other techniques as long as the final lists meet those accuracy standards. Please quote your rate per 1,000 validated leads. Deliverable for each city: a clean CSV or Excel file showing name, title, company, website, email, phone (when available), and city. Payment will be released once random sampling confirms the bounce threshold and role criteria. I’m ready to move quickly with the right partner—show me how you’ll keep my data clean and my outreach effective. Include “Project ID: 55LG” at the very beginning of your bid so I know you read these instructions.
