[P] Infinite Shelter

I have an idea. I've been meaning to create this website: 3dbusinesscards.com (or some similar name). I've printed a few business cards for myself on my 3d printer, and they look cool. Unique, impactful. Business cards are not dead, and I'm sure some people who are regular conference attendees would be interested in printing theirs in plastic.

So the website should give people the ability to select one of the available themes, modify it (change font, position, add/remove lines, etc), and place an order.

The design should be complete, every necessary page (it's an eCommerce site, after all), looking good on desktop and mobile, and be minimal. So, although you can draw inspiration from vistaprint.com, I want my resource to be much, much simpler and more minimal. The main part of the design would be the workflow to customize the card, change fonts, etc.

If you're interested in taking this on, we can do this project. What do you think? What would be your estimate (time and cost) on this? And if you have clarifying questions I'll be happy to answer them.
