Custom 3D Model for Unit Configurations

I am looking for someone skilled in the graphic design department, able to create a 3D model of different sized trailers, which will allow customers to customize & add equipment to their needs, keeping in mind the weight limit and fitting to scale. We are looking for an addition to our website, where customers will be able to add or delete certain pieces on their trailer. We would love a website customizer/builder similar to this one: (https://phiber-dash.netlify.app/). Our company is a short-line machinery dealership located in North Dakota, looking to provide more services and customization for our customers! We hope you can help us!
