smart glasses

My goal is to create a pair of augmented reality smart glasses (building a prototype smart glasses) that meets a detailed list of specifications(i am working on a augmented reality mobile application for indoor navigation, and im looking for someone to only 3d print the glasses and do the technical work, i will send the Design of the glasses ,i just need a augmented reality arrow to be shown on the lens, so it should work as this -> i will open the navigation on the mobile application and connect the smart glasses to the phone and it will show the way to the destination with an arrow so it will tell you go right , left , back, straight). It is important to me that the glasses have good battery life, as this is a key feature of the product and to be neatly and professionally developed . The glasses must also incorporate the latest in augmented reality technologies to provide users with a truly innovative sensory experience. The wearable technology should be intuitive and easy to use in order to offer the best experience for users. connection of the glasses to the phone will be using raspberry pi zero .To make it clear i just want a working prototype not a fully launched one (POC) PROOF OF CONCEPT
