Finding talent within rendering

Wow, definitely. This is impressive work and requires a special skillset as well as equipment.
I was also under the impression the OP has much simpler needs.
But without more info, who is to say?

Just as a reference where some recent grads and students are today, I bookmarked Dustin Lee.

I have never met or know Dustin and don’t know if he does freelance but in terms of output, it’s pretty close to the extent what can be done with keyshot/PS, I’d say.
After this, I’d also recommend a specialist with special software or agency.

We are using XYZ as well, along some other but are also building our in house capabilities.
Doing stuff inhouse has so many advantages. Especially when it comes to convey the feel, brand values and intent of the product.
Here at Logitech, the Industrial designers do the vis and render-work for pretty much all internal comms, then the render experts take over for consumer facing work, using the ID renders as starting points.
