Looking for a spherical Earth model with topography and texture

As you can tell in the title, I’m looking for a model of planet Earth with topography. What I mean by this is that I need a model that has mountains, etc. modeled for parts that are visible from space. Additionally, I need the ocean floor included (I don’t want water in the model at the moment). The ocean floor should be flat (this will be a lot friendlier for rendering in my game and doesn’t really matter since I will add water in the places where it should be). If you have any questions please feel free to ask, and I greatly appreciate anyone willing to take time to do this for me. Thanks.

EDIT: Also if you are interested in helping me with this game feel free to PM me and I’ll give you more details, currently I am looking for a proficient 3D modeler.
