Augmented Reality - Full body recognition with Camera input

We want to make a long LED display for our customer to come in and stand in front of them and the camera will click a full photo of them as they stand in front. the photo will be a full standing shoot and then when selected the whole image clicked of that person will become a selected model that will be available. It will cover the whole body of that picture (Only the body) with the model we have selected. Like a coca cola can will take place of the persons image and then when moved, the coca cola can will mimic the persons movements. (Details will be shared to bidders who can demonstrate their work only, the project is high tech and only bidders with higher ratings will be considered). Only the bidders who can demonstrate their existing work will be considered and then interviewed for further elaboration. Unity 3d is the platform that we are looking for and would appreciate if the bidders can share their existing work (Downloadable/workable) in their proposals.
