I need a Simple app creating for Augmented Reality programme

Hi, I am looking for somebody to create a very simple user friendly App for me. We currently have a 3D image in Sketchfab that we would like the user to be able to put in their garden using AR but a user has to search us to find our model. We want somebody to be able to download our app and see only our videos and models.

This is the model we currently have. We design and make gardenrooms www.gardenplex.co.uk and we want people to be able to place our 3D model in their garden using AR.

If you can help with this please get in touch, thank you
