WordPress Addiction Rehab Directory Development

We are building a scalable WordPress-based addiction treatment directory at AddictionRehab.com. The site currently runs on WordPress with ACF Pro and needs a complete backend architecture rebuild to support thousands of listings across every city, state, and country globally.

What we need built:

-Custom Post Type (CPT) for rehab facility listings with 50+ ACF Pro fields covering clinical data, operational policies, insurance, amenities, and lifestyle factors (smoking policy, phone blackout periods, pet policy, family visitation, treatment philosophy, dietary options, costs, etc.)

-Geographic taxonomy system (Country > State/Province > County > City) that automatically generates archive/directory pages at every level from a single template

-SAMHSA API integration to bulk import all licensed US treatment facilities as listing stubs

-Google Places API integration that auto-populates and periodically refreshes ratings, reviews, photos, hours, and coordinates using a stored Place ID per listing

-WP All Import Pro pipeline for ongoing bulk listing management via CSV

-FacetWP or SearchWP faceted filtering on archive pages (by insurance, level of care, amenities, location)

-Single listing page template that renders all ACF field data cleanly for end users

-Full schema markup on every listing page (MedicalBusiness, GeoCoordinates, PostalAddress, OpeningHoursSpecification) mapped to ACF fields via Rank Math Pro

-Redis object caching configuration

-Admin workflow optimized for managing listings at scale — adding a new listing should take under 2 minutes

Current state:

-WordPress staging environment already set up
-ACF Pro licensed and installed
-CPT structure partially defined
-Rank Math Pro installed
-Cloudflare configured

You must have demonstrated experience with:

-WordPress CPT and ACF Pro architecture at scale
-External API integrations (REST APIs, Google Places API)
-Directory or listing sites with thousands of records
-FacetWP or SearchWP
-Geographic/location-based query optimization in WordPress

To be considered, answer this in your proposal: Describe a WordPress directory or listing site you have built that used custom post types, ACF fields, and at least one external API integration. Include a live URL if possible.
