Flask Data Entry Site Build

I need a small, self-contained web application built with Flask that lets users submit three fields—Name, Mobile, and Email—through a clean, responsive form. Submissions should be stored in a SQLite database, and I’d like a lightweight admin area (a simple table view with pagination or basic search is enough) so I can review, edit, and delete the records.

Please structure the project so I can run it locally with a single command (virtual-env, requirements.txt, and a concise README explaining setup, routes, and database schema). Keep the code readable by adding inline comments where helpful and grouping logic into blueprints or similar best practices.

Deliverables
• Flask project folder with templated front-end form
• SQLite schema and migration or init script
• Admin view (password protected) listing all entries with basic CRUD controls
• README covering installation, running the server, and file structure

Timeline is tight—ideally everything wraps up within 2–3 days. Share links or repos of any comparable Flask data-capture tools you’ve built so I can gauge fit quickly.
