We would like an explainer video of our technology

We would like an explainer video along the lines of [ https://www.youtube.com/watch?v=e8orJ-v_-H0 or https://www.youtube.com/watch?v=2pp17E4E-O8] aligned with a script we have drafted which is 600 words and the voice over is approximately 4 minutes 20 seconds.

The script contains assets you will need to create (we will be able to provide adobe stock images and videos like the ones attached but you will need to be able to build out from these) as it is about cells and T-cells in the body.

To give you an idea of the content, this is the first paragraph: "Our body relies on T cells, the natural killer cells, to find and destroy dangerous threats such as cancer.
But cancer cells can disguise themselves, allowing disease to grow unchecked.
One of the biggest breakthroughs in cancer treatment has been the development of T cell engagers. These drugs act like a bridge. One end attaches to a cancer cell and the other end attaches to a T cell."

We have already created the voice over and a storyboard guide (not prescriptive) which we will send upon engagement.

The finished article must be able to be embedded our website but we are agnostic as to the software used.

We are looking for someone experienced and with work of similar quality to the examples we have given. This is essential.
