Build a scalable, SEO-friendly directory website listing 15,000+ Indian schools & colleges (WordPress or custom CMS)

I’m seeking an experienced web developer/agency to build a comprehensive education directory website. The site should list schools, colleges, and universities across India (Pre-K to higher education). The goal is to let students, parents, and visitors search, filter, compare, and apply to institutions — with detailed listing pages, course/fee data, admission information, and more.

Scope & Deliverables:

- Set up WordPress (or CMS of choice) on hosting.
- Build directory functionality: listings for schools/colleges with details like name, institution type, state, city, board/course type, contact info, admission info, etc.
- Bulk import/upload of ~15,000 institutions via CSV or script.
- Implement search & filter (by state, city, institution type, board/course type, etc.).
- Responsive design (desktop & mobile) with fast loading.
- SEO-friendly URLs, metadata, and site structure.
- Admin panel to add/edit/delete listings easily.
- Optional: lead-capture or inquiry form for users interested in institutions.

Required Skills:

- WordPress (or CMS) development
- Directory / listing-site experience
- Bulk data import/database handling
- Responsive UI + performance optimization
- Basic SEO best practices

What I Expect from You:

- Provide a functioning directory site with full import of provided data (or template ready to import when data is available)
- Clear documentation on how to manage & update listings

I will share the reference website on chat. Thanks...
