Need an application

We are making a photo booth which print photos from Instagram instantly. It has a big touchscreen monitor, computer, printer, money acceptor. So we need to make an application which will work with Instagram. How it works: 1)You search photos by #hashtag or @nickname (if @profile is closed you can enter password and profile will open); 2)You chose photo and quantity 3)You insert credits to money acceptor 4)Wait for photos Later i will give a video how it works.
