Create 3d real life images from a 2D image

Hi

We have 5 x 3D renders that need added detail to make them look more real, like added shadows, textures etc.

We also have 5 x 2d drawings that need to be made into 3D real life images.

See attached the example of 3D and 2D visual and an example of the level of details we would like them to have,

The images will also need to be scaled to a large size so they can be used on a billboard

I hope this is a job that can be done.

Thanks
