Is everything provided, as in trees, people, reference of texture scales/look, etc...? Are you using background image for the plantlife? There are drag and drop meshes in C4D to account for those things as well, so it wouldn't be hard to do depending on what all you need in there that would be custom. Just need to plug in all the textures and tweak the shaders, then light the scene. I could probably pump out a scene like that in a couple of hours apiece, that includes render time, depending on what all you want in there.
