Create a 3d model for an object and render it into a picture in a realistic way

This project is about creating a 3d model for the LG heat pump. Once created the model should be inserted in the designated area marked in pic-1. The object should be placed on top of supporting legs (some suggestions can be provided, but how the legs should look like is up to you to decide). More pictures and video can be provided. The render/import should be done in a realistic way taking into consideration, the light/shadows etc.
