About this gig

Need real prospects, not a recycled database dump? I build a fresh B2B lead list for your exact niche and area, sourced from each business's own public website, so every row can be checked.


What you get (CSV/Excel):

- Business name, website, city/state

- Phone, and email where the business publishes one

- A source link for every row, so you can verify it yourself


Built for agencies, sales teams and service businesses selling to contractors: roofing, HVAC, plumbing, electrical, general construction and more. Other B2B niches on request.


How it works:

1. Tell me your niche, location and ideal customer

2. I research and verify each business from its own website

3. You get a clean, de-duplicated spreadsheet built fresh for your order (never a resold list)


What I don't do: no purchased databases, no scraping behind logins, and no guessed emails. If a business doesn't publish an email, the field stays blank instead of invented.


Message me before ordering if your niche is unusual and I'll confirm it's a good fit.
