Simple geometric 3D model needed built

Hi everyone,
I used a stock photo for a print project and the client requested modifications to this image. It’s a relatively simple design and I could probably do it in Maya, but lighting scenes (global illumination, radiosity, and things like that) are my weakness.

Here is the photo I used:

I tried contacting the designer on iStock but it’s been over a week and haven’t heard back from them.

If you’re comfortable recreating this model (preferably in Maya just in case I need to edit it), please contact me with your price and turnaround time.

The client does have some minor modifications to the model so please don’t build the model before we chat. I don’t want to waste anyone’s time.

Payment can be handled through PayPal.

Thanks!
