Not so long ago I myself was looking for solutions to this problem and to me recommended to contact the company sketch design to html https://www.psd2html.com/sketch-to-html.html where listened to me carefully and provided a great solution. Therefore, I can tell you with confidence that you need to contact PSD2HTML
Well, I do not really know certain companies that could deliver this kind of services. However that is not so tough actually. And there are actually a hell a lot of tutorials regarding this conversion on the internet right now. However you might be well informed about the CSS and you have to know at least something about programming. Surely it is not the toughest thing in programming, however it is not easy at all. I never actually had such a need, right now i need to install the magento 2 page builder for my website. In case you still need this conversion, just google it, you will find an answer.
oh, so is magneto 2 even better than compared to the first version of it?
