Civil 3d Road Network Design for University Project with 3d House and Tree Models

I need a skilled freelancer to assist with a university project involving road network design using Civil 3D. The project requires the creation of a main road and two secondary roads. Additionally, eight simple house models and various tree models need to be integrated into the design. These models can be created using software like Sketchup or similar 3D modeling tools, focusing on simplicity rather than intricate detail. I will provide a base DWG file and detailed instructions to guide the project. The primary goal is to produce a functional and visually coherent road design suitable for academic submission. Expertise in Civil 3D and basic 3D modeling is essential.
