Animated 3D render

Hi. We’re looking for someone to manipulate a .stp 3D render in a few ways below. The output will be used on our website and various social channels. So we're looking for something high quality.

The changes that we are looking for are:
- Change the colour of the render to yellow (exact details to follow)
- Make the render rotate on it's Y axis
- Annotate the final render using arrows that point to various parts of the render, that can lead to captions that explain the various functions of the render. Here is a link to a (bad) example! -

We're looking for x2 files delivered:
- One which is just the manipulated rotating render
- One which is the above including the captions

If you can show examples of similar work/ projects that you've conducted, that would be helpful.

Thanks
Carl
