Verified Comcast Leads Needed

I need a fresh batch of Comcast-domain email leads with real estate as the top priority. Civil-engineering contacts come next, and I will also consider real estate ,crypto or any other sector you already have as long as they do not dilute the main focus. All addresses must be verified, active, and unique to avoid bounces. Nation-wide coverage is what I’m after, so please draw from every state rather than limiting the list to a single city or region. My working budget is $20; tell me how many solid, ready-to-use records you can deliver for that amount and when you can hand them over. Deliverables (single file, XLSX or CSV): • Email address (must be @comcast.net) • Sector (real estate, civil engineering, crypto, etc.) I will release payment once I spot-check a sample and the bounce rate stays under 5 %. Looking forward to your numbers and turnaround time.
