Animated hi-tech product rendering video using Keyshot, LuxCoreRender etc.

I am looking for a highly skilled professional with extensive Keyshot or similar experience and design flair to produce some amazing product videos of our hi-tech electronics audio products.

You will be given Keyshot still renders of the outside of the product and its component parts, but will need to add detail to internal parts such as components on the circuit board and speaker driver details (similar to the examples shown here).
The product comprises a charging case and a pair of wireless earbuds. You will need to show the earbuds in the case and the case opening and then the earbuds coming out of it and the rest of the video will focus on details about one of the earbuds.

The initial task is to produce a video to sell a new pair of wireless earphones with a video similar to this..

(note this video is nothing to do with our company, it is just one that we have found on YouTube)

Here are some other videos of a similar quality that inspire us:-

Length should be around 2 minutes. A much shorter edit approx 15 secs long is also required.

A storyboard will be provided however I would like the chosen designer to use their own creativity to contribute and
enhance to achieve the best possible result.

I have no idea how much this will cost so have put USD400 down for starters. Maybe it costs more?! Maybe you are prepared to do it for less? Quality of the end result and design flair is more important than price to me. Please bid what you are prepared to do this job for to the quality shown here.

Thanks!
James
