apparel design app

the project is simple .. i have a website and i need to add an online web app to design custom apparel with it (i need some tools to add more apparel in the future in the app) also i have some sorts of my products .. when i pick up for instance a polo shirt it should open the web app and the polo shirt should be ready inside the app to add some (color .. text .. art) This link is helpful .. i need an app exact the same in this website .. also it must be responsive to all different devices as my whole website is responsive [login to view URL]
