I want a secure, easy-to-use portal built into our existing website so my sales team can log in, key in a project’s specifications and the quantity of items, and receive an instant, accurate price plus a ready-to-send proposal. The calculation is based off a data matrix and user selections/input. a fixed rate is applied to each item. That rate needs to live in a small admin panel where I can update it at any time. Later we might expand the form to capture client details, so please structure the database with that in mind. Once a job is sold, the project may live here and will eventually include all correspondence, shop drawings, approvals. Here’s the flow I have in mind: • Employee signs in with existing credentials. • A clean form asks only for project specs and quantity. • The system multiplies quantity by the stored fixed rate, displays the total, then generates a branded PDF (or Word) proposal for download. • An admin area lets me edit the rate, manage users, and review a log of every quote created. Use whatever modern stack you prefer—PHP/Laravel, Node/Express, or Python/Django are all fine—as long as it’s secure, responsive, and easy to maintain. A lightweight front-end framework (React or Vue) for a smooth user experience would be welcome but isn’t mandatory. Deliverables • Integrated portal with login, form, real-time pricing, and proposal generation • Responsive design that works on desktop and mobile • Admin dashboard for rate and user management plus quote history • Source code, deployment notes, and a brief hand-off session Acceptance criteria • Only authenticated users can access the form • Prices calculate to two decimal places with no lag • Proposals download successfully across common browsers • Code passes basic security checks (OWASP top ten) Once delivered, I’ll run a quick test with the team; if everything performs as described we’re good to go.
