Design a portfolio website for my photography business

I am looking for a website that I can use to show my portfolio of my photos. I want a simple, easy, yet elegant website. I will only need about 3-4 pages.
Home Page, About us Page, Contact us Page and Portfolio/Gallery Page. I would also like a calendar on the Contact Page so clients can see my schedule and book on free dates that I may have.

I already have webhosting in place and I already have a logo.

Colours I would like are:
Blue and white
Or Dark gray mixed with light gray

I am doing school photography, family photography as well as individual modelling photography.

Business name is: NKT Photography

I would also like the website to be HTML 5 as its more optimise for ipad which I always use.

I would like this website ASAP as many clients are asking to see my work.
