Visiting Card Generator UI/UX

I need a straightforward, professional-looking UI/UX for a visiting-card generator that works smoothly on both desktop monitors and mobile phones. The visual tone must feel corporate—clean lines, neutral colours, restrained typography—rather than playful or overly vibrant.

Scope
• A compact screen flow that covers the key steps: home, template selection, card-generation and design upload.
• Template selection screen should let users browse ready-made designs.
• Card-editing screen must offer basic text fields and logo upload placeholders, laid out so the user can instantly see changes.
• A 2D flat preview panel appears before the user hits Download, giving a true-to-size view of the card.

Please deliver a clickable Figma (or similar) prototype with desktop and mobile breakpoints plus exportable assets or style guide notes so a developer can build from it quickly. Tight, minimal documentation is fine—I mainly need the screens, consistent spacing and colour specs.
And most importantly I require a landing page design with Images and text contents that could be implemented as such. Also make sure to provide me with a file of all the images used in the Figma design.

If you find this interesting lets get in touch and discuss the complete workflow.
• This website is already implemented with a minimal UI, and I do like to get a professional touch to it.
