Unity AR GPS + Location/MapBox Art Project

PLEASE READ BEFORE BIDDING Looking for Unity Developer that can build Augmented Reality using the Unity AR Foundations kit, MapBox and GPS or Unity AR+GPS Location Concept: When the user is near preset GPS location, can view 3D object with Camera. I would like this to open from the viewer's phone web browser. If not able to create a web-based app, I am open to either an iPhone/Android app if it works out-of-the-box. There are 9 locations in total. I will provide the 3D files. • Need a web browser-based link but open to Android iOS app. • At the GPS location, the STL file 3D Object will display. This will be at a fixed location, not moving. • The project needs to be complete and presented as an art project to be used by multiple viewers. I need to place the 9 AR objects in the world and be able to see them when the viewer opens a web link and approaches the GPS coordinates. This should be a finished product. NOTE: I am not building a game. The images attached are used just as an example of how I want the viewer to see the 3D object, being able to walk around the object and view all sides.
