3D visualization platform

Hi, I am architect. I model my projects in 3D using Revit and Unreal engine software. My idea is to have a website where I can show my projects to my customers as a videogame. For example, I model a 3D house for my client, then I upload this model to the platform, I share the link to the customer and he can enter the 3D model as a videogame, so he can walk around and inside the house. The most important think is that te model may seem realistic, so the target is to show the model renderd in real time as real as possible without the need of downloading any software in the customer PC. I need a freelancer expert in unreal engine that can prepare a web platform where I can upload directly my 3D models and then the customer can "play" directly on each model and walk and see all the details of the design.
