Build a Responsive Website for a IT Services startup

We are looking to build our company website. Following are few things we are looking at: 1) Website should be responsive 2) Should be easier to add new sections 3) Use of opensource frameworks only, preferably bootstrap. 4) Should be able to suggest color schematics and layouts, so that we can take a decision on these 5) Some basic animations in required sections (content fade in/out, zoom in/out etc.) We expect you to showcase some of your previous work or own projects We will be interested to see if you have some templates to choose from.
