B2B Lead Generation for Home Service Businesses (HVAC/Plumbing/Electrical/Garage/Septic/Chimney)

I am looking for a B2B Lead Generation and web research specialist to build a highly targeted list of 150 mid-sized residential home service companies (HVAC, Plumbing, Electrical, Garage Door, Septic, or Chimney shops) in the United States. Target Regions: Focus exclusively on the metropolitan areas of: Dallas (TX), Atlanta (GA), Houston (TX), Phoenix (AZ), and Tampa (FL). Company Size Criteria (Targeting 5 to 25 Trucks/Techs): Tradesmen rarely list their exact truck count online, so you must use these smart proxy metrics to identify mid-sized operations. A company qualifies if it meets the Review Metric for its specific trade, backed up by at least one of the Supporting Green Lights. 1. The Review Metric (Based on Trade): TIER 1 TRADES : (HVAC, Plumbing, Electrical): Must have 75+ Google Reviews (these are high-volume emergency trades). TIER 2 TRADES : (Garage Doors, Septic, Chimney, Roofing): Must have 40+ Google Reviews (these niche trades naturally collect fewer reviews). 2 SUPPORTING GREEN LIGHTS (Look for at least ONE of these to confirm size): Visual/Website: Their website features a "Meet the Team" page, photos showing a fleet of multiple wrapped trucks, or text mentioning they are a "growing team." Hiring Activity: They are actively running job postings on Indeed or ZipRecruiter looking for field technicians, installers, or office dispatchers. Professionalism: The business owner, General Manager, or Operations Director has a personal profile on LinkedIn. (Note: Completely skip 1-3 man bands, solo trunk-slammers, or tiny shops with under 10 reviews and no digital footprint. We only want growing, mid-sized companies). Technology Filter (Crucial): They must currently be using lower-tier competitor software (such as Jobber, Housecall Pro, FieldEdge, or Service Fusion). You can verify this by checking their website's "Book Online" widget, or by running their URL through tools like BuiltWith / Wappalyzer. ***CRITICAL: Do NOT include any companies that are already using ServiceTitan.*** Deliverables Required in a Google Sheet / Excel: Company Name Industry / Trade (e.g., HVAC, Septic, Plumbing) City, State Website URL Proxy Used to Verify Size (e.g., "120 Google Reviews," "Active Indeed ad," or "Fleet photo on site") Current Competitor Software Found Owner, Partner, or General Manager's Name Owner/GM's Direct, Verified Email Address (Verified via Hunter.io, NeverBounce, or similar) To apply, please provide a brief description of your experience with B2B tech-stack scraping and list building. I will start with a paid 5-lead trial before moving forward with the full project.
