3D static Rendered images x 4: Gold / Silver reflective shapes for website background

Industry: Lifestyle/Travel
Design details: Hi there.

I need 4 images created in 3D, with shiny metallic reflective surfaces (two gold, two silver), to be used as part of a photoshop image for the background of a website.

We've started creating the images in Photoshop, but the client wants a super shiny surface, and this can only be achieved in a 3D program, hence I'm turning to you good people of PPH. I can supply the vector shape, and also have the example, as well as the first draft images.

See the golden Gs? We require that surface, but using the shapes below. Each shape will have a slightly different background, as images below.

What we've got so far:
Image 1 - gold Circles: https://www.dropbox.com/s/e2tbqjdu1y8wj2b/gold.jpg?dl=0
Image 2 - gold trellis: https://www.dropbox.com/s/qepazibzi39fz06/TeaCandles.jpg?dl=0
Image 3 - silver triangles: https://www.dropbox.com/s/x3flirtl5yhcinf/Diffusers.jpg?dl=0
Image 4 - silver squares (this will change to straight lines): https://www.dropbox.com/s/36gmzd3hln738fy/Classic.jpg?dl=0

So what we'll essentially need is, an image rendered in 3D, against a transparent background, like this (Image 4 will change slightly, so I'm not adding it here), that we can use in photoshop to create the background image.

I also know to get a good reflective surface, you need image to reflect off, so I have one as well that can be used. I can supply the flat vector shapes as well (the circles, trellis work, squares and triangles). Ideally I'd like these to have beveled edges like in the example image.

I need it as soon as possible (always!) but I also realise that these shapes will need to be built in 3D, and rendered, all which takes time.

If there's any additional questions you might have, please let me know. Thanks in advance!!
