Ask HN: Know of any place to buy UI templates for SaaS websites?

I can do the backend/databases etc, but I can't make a website look nice for the life of me.

I've been looking through the usual places like themeforest etc. Something or the other is missing - for example, most have landing pages only.

Know of any HTML templates (bootstrap, plain html/CSS, foundation...whatever) that I can buy and customize? Landing page, features page, testimonials page, pricing page, forms, about page and maybe an admin page? Nothing fancy, no flashy graphics - just well written HTML/CSS, nice typography, clear navigation that can be easily customized (if it is just black and white, even better!)
