Using Augmented Reality Design and implement a 3D Application

I am looking for a freelancer who can design and implement a 3D application using augmented reality technology. The primary purpose of the application is for education, and it will be available on both mobile and desktop platforms. Since I do not have any specific 3D models or assets, I am looking for someone who is skilled in finding or creating them. The ideal candidate will have experience in designing 3D applications and working with augmented reality technology.
