Jason Schuller: http://jason.sc/
A very good minimalistic webdev. A lot of his templates can be downloaded for free at https://jason.sc/work.

AJ: https://aj.lkn.io/
Makes awesome templates on https://html5up.net/ (for free) and https://pixelarity.com/ (paid).
He’s even made a simple online webpage creator over at https://carrd.co/ (simple to use).

BlackTie: http://blacktie.co/
Bootstrap webpages.
Not as great as from the two designers above, but still pretty well-looking.
