As website development is my primary skill I have developed a bunch of websites as you have attached in your sample.
I have hands on latest freeware and rich UI frameworks like Angular.js, Bootstrap, Node.js which in turn can make your website with rich but lightweight UI.
Outline :
1. I will divide the website into unites as
a. every tab as a different Unit
b. Dashboard/Homepage as different Unit
So that if needed you can have a look at the developed work on daily basis.
If you have any further queries, you can reach out to me by personal message here.
