This is nice, simple and easy to use. I run a small print shop and have an idea to build something like this, where my customers can upload their design and order from our site.

Is it possible to build something like this without back-end work? Can I build this on static site? I know little bit of JavaScript. We build our static site with Jekyll and GitHub.

Edit: No need to edit the file. They can only upload and order (maybe send it as an email when they push "order"?). That's it, nothing else. Thanks!
