Building a $0 Customer Acquisition Engine: How We Scaled a Valet Trash Service to 14 Houston Counties with VAPI, Make.com, and G

OPENING PARAGRAPH: We built an automated sales system for Quiet Hours Valet that generates qualified leads across all 14 Houston counties—without a traditional sales team. Using VAPI for AI-powered phone calls, Make.com for workflow orchestration, Google Apps Script for CRM operations, and Apify for real estate data scraping, we created a vertically integrated lead generation pipeline that costs less than $2 per qualified prospect. This technical breakdown covers our exact stack implementation, from property scraper configuration to inbound call routing, the county-level zoning data we extract, and how we handle 200+ daily automated calls on Asterisk PBX infrastructure. If you're building B2B services in local markets, this is how to eliminate manual outbound dialing entirely.
