Internal Admin Web App Build

We are seeking an experienced developer to create a private internal web application designed to streamline operations by replacing spreadsheets. This web app will require user login for 1-3 users and will include key features such as an SKU-driven item catalog with CSV import capability, order creation functionality (including customer details, address, and scheduled delivery), and a cut list section to manage item quantities and lengths with automatic total calculations. Please note, this application will not process payments and is intended solely for internal use.
