Summary after photo shoots

I have five images which are going to be my finals. I need one more image. While I am searching for a model to take the sixth image I can move on to the next stage which is photo manipualtion. My aim is to get the consistent and uniform look of the images to keep the visual cohesion/continuity. I’d like to increase the contrast to boost the vividness of tones and colors. Also I'd like to create the same background for each image (probably using gradient tool in Photoshop) to make all objects look shiny and gold I may use some 'gold shiny textures' from the free internet texture stocks. I also will use dodge and burn tool to increase the highlights to make it look shiny.
