Internet site programming - Explanations

We are an advertising agency, based in Athens Greece and we would like to create a new web site for our company.

We will be designing the site ourselves, making it quite impressive, which in terms of programming means that we would need a programmer speciallized in HTML5 to help us.

It will be a dynamic site.

Attached you will find a site tree of our site and an example page (Services page).

The explanation of the page you see in terms of movement is:

At the menu on the left when you go to the desired category thsi turns red.

The tree is flat into the page and then it stands up, with a smooth movement.

It shakes and the leaves fall of the tree, coming to a stand still on the page (not falling down).

Each leaf will represent a service. Once you go on the leaf it will shake and a small text describing the service will appear.
