Build Homeowner Lead Generation System for Painting Company

Build a Neighborhood Homeowner Lead Generation Platform (Real Estate Data + CRM) Project Overview I'm looking for an experienced Python developer/data engineer to build a web-based application for my painting company. The goal is simple: I enter a property address, click **Search**, and the system returns nearby homeowners within a selected radius. This is for neighborhood marketing after we complete painting projects. Required Features CHECK FOR DNC The application should: * Search any U.S. property address * Allow radius selection (0.25, 0.5, 1.0 mile) * Return nearby residential properties * Display results on a map * Export results to Excel and CSV * Support GoHighLevel CRM import * Be fast and easy to use ## Data Desired (where legally available) * Homeowner name * Property address * Mailing address * Owner occupied (Yes/No) * Square footage * Year built * Estimated home value * Lot size * Phone number * Email address ## Bonus Features * Filter by: * Home value * Square footage * Year built * Owner occupied * Remove duplicate records * Exclude existing customers from a CSV upload * Save previous searches * Batch search multiple addresses * Generate neighborhood reports ## Technical Skills Looking for experience with: * Python * APIs * GIS / mapping * Real estate/property data * Data enrichment * Google Maps * GoHighLevel API (preferred) ## Important I'm **not** looking to scrape or copy proprietary databases or software. The solution should use legitimate APIs, licensed datasets, or public records and should be designed so it can be used in compliance with applicable marketing and privacy laws. ## Deliverables * Working application * Complete source code * Installation instructions * Documentation * Ability to add additional features later ## When Applying Please include: 1. Similar projects you've completed. 2. Which property data APIs you recommend. 3. Your estimated timeline. 4. Estimated total project cost. 5. Any ideas that would make this platform even better. This is intended to become a long-term project. If the first phase goes well, there will be additional work to expand the platform.
