Build Fress 100K US Company Directory with CEO

I want to launch an online directory that features detailed profiles for roughly 100,000 companies operating in the United States, each profile displaying the current CEO’s name alongside basic company information (location, sector, short overview). The core objective is straightforward: visitors land on the site, look up a company, and immediately see who runs it.

Key deliverables I expect from you:
• A fully-functional, responsive website that can comfortably handle at least 100K records without slowing down.
• A clean back-end structure (relational database or equivalent) so I can import, update, and export the company/CEO data in bulk whenever needed.
• An intuitive front-end where users can quickly browse or search by company name, state, or industry. I am open to whichever tech stack you feel is most efficient—WordPress with custom plugins, Laravel, MERN, or something else—so long as performance and scalability remain solid.
• Data accuracy is critical. If you already have reliable data sources, great—otherwise outline how you plan to gather and verify the CEO names before we begin.

Timeline and workflow: After we align on the structure, I’d like a small proof of concept (perhaps the first 1,000 companies) to confirm layout and data quality. Once that is signed off, we can move in larger data batches until the full 100K record set is live.

Please outline your proposed stack, any previous large-scale directory work you’ve done, and how you plan to secure and validate the database. I’m happy to answer questions quickly so we can get moving.
