B2B Real Phone Number Lead Generation Expert

Description:
Hi, I’m looking for an experienced phone number leads generation specialist to help me set up a scalable system for finding B2B leads in the United States.

I have two possible options and I’m open to either:

Building a simple, reusable system/tool or workflow I can use myself long-term
Teaching me how to find and build high-quality leads myself step-by-step

What I need:

Research of relevant USA-based companies in my niche
Finding publicly available contact details
Publicly listed real phone numbers
Identifying decision-makers via LinkedIn or company websites
Organizing everything into a structured spreadsheet or CRM format

If building a system:

I want a simple tool, workflow, or setup I can reuse repeatedly
Must rely on compliant and publicly available data sources

If training me:

Step-by-step guidance on how to find leads manually and efficiently
Recommended tools and workflows
Best practices for outreach and list building

Requirements:

Proven experience in B2B phone number leads generation (USA market preferred)
Strong research and data organization skills
Ability to either build simple systems or teach clearly
