Animated Isometric Explainer Video

I'm looking for someone to create an animated explainer video to describe a technology solution for industrial rail yards for our website. There are only about 10-12 steps/sentences that need to be animated. You will need to animate a complex rail yard (multiple tracks and switches), cars moving around the tracks with multiple cars on multiple tracks, an employee walking around, hardware with lines connecting the hardware to different locations, and then a rendering of our technology solution and dashboard. I already have some concepts drawn out at a very high level and a basic script developed. I don't need a voiceover yet, but would need to have text. Looking for quick turnaround, this needs to be completed by May 31. Please provide links to the most relevant work you've completed for me to review. I will make a hiring decision today (May 27th). Responses will not be considered if you do not include a link to relevant animated explainer videos that you've created.
