Big Commerce Expert required

Ok I have already a live website ecommerce via Big Commerce but I wish to add an interactive front page with features other than just a slider and products. Here is my site: [login to view URL] and here is an example of the sort of front page I wish to develop and add to my site: [login to view URL] Is this possible within the locked php of big commerce? I do not have unlimited funds and am unsure of the complexity of this project so invite quotes... thanks
