I need a Realistic Product Image Created for Marketing a Product

I need a photoshop Exper to create a hyper realistic Image for a product based on the 2 images attached.

One is a physicalprototype made of wood showing the 4inch x 4inch size - though this prototype is too thick, it should be slimmer. - The second Image is my very crappy photoshop rendering of a device in gold.

I would like a reacreation of this to look realistic. I would like the block to have a marble effect as this is the material we are chasing to use. I would also like the Attached Logo added o the block to look gold and indented on the marble surface.
