Verified CEO Lead List Builder

I need a fresh, dependable list of decision-makers—specifically CEOs or Founders—working inside four service-based niches: landscapers, contractors, plumbers, and solar companies, pool builders, renovation, electricians,Please note that these lead lists are for cold callers and appointment setters. Please skip the usual scraped directories; every record must be hand-researched, matched to my criteria, and fully verified.

Scope of work
• Research prospects that fit BOTH filters: job title is CEO or Founder.
- These leads should have No websites or bad or outdated websites strictly.
• Collect core contact data: first & last name, company, role, company website, phone (verified), LinkedIn URL, and location.
• Verify Phone numbers so the list is ready for outreach with a bounce rate under 5 %.
• Deliver the final file as a clean CSV or Google Sheet with separate columns for each field.

I’m open to your preferred research stack—as long as the output is accurate for cold calls.

When you reply, let me know:
1. Valid numbers with verified source
2. A brief note on how you confirm job titles and industry fit.

I’ll review a small sample first; once it meets the accuracy check, we’ll move ahead with the full batch.
