Word Template Merge Web App

I have roughly 25 Microsoft Word templates with fixed wording and clearly marked placeholders. In seven days or less I need a working web application that lets a registered user fill a form, upload any required pictures, pay through Stripe, and instantly receive a freshly generated .docx where both the text and the images have been merged into the correct spots.

Here is what must be in the finished product:

• Secure authentication with two roles only—admin and user.
• Stripe integrated so a payment successfully unlocks the generate-document action.
• A backend service that stores the templates, injects the incoming text and images, and streams the completed Word file without errors or broken formatting.
• An admin screen where I can upload, remove, or edit the twenty-five templates in the future.

I’m flexible on the tech stack as long as the template processing is rock-solid (docxtemplater, python-docx, Aspose, or a similar proven library are all fine) and the code is clean enough for me to maintain after delivery. Front-end polishing is welcome but not mandatory; reliability and meeting the seven-day deadline are.

When you apply, confirm you have handled Word templating with mixed media before and can devote the full week to this build. I will award quickly so you can start immediately.
