Since you mentioned that this would be an internal web page for your friend's company Netlify does not seem to be the best answer for that. When there is already a working nginx just push it via FTP. If you know how this is done, do it like that.

Sure there are those "cool" new ways but when you know how this could be done in a way you are familiar with go for it.

But if you have the time and the page does not have to be running asap go that way with building it around Vue.js and webpack etc.
