I am looking for an isometric video of approximately 60 seconds.

Howdy, I am looking for an isometric video of approximately 60 seconds. It should be an explanatory video, which talks about online training and job search platform as well as how to use it; both for normal users and corporates. We are an engineering company, providing skilling courses for engineering graduates and job-seekers. Need an isometric style video explaining the concepts in a concise clip, of up to 60 seconds. My budget for the same is around USD 150$. If you are interested in the project, you need to create a SHORT DEMO VIDEO of 20 seconds for me to see. If I am satisfied with the quality of your work, only then I will place an order. Pls contact me only if you are willing to make a free demo video and show me. The demo video should not be from your previous work; instead it should be made on the basis of details that I send you. Please don't show me your previous gigs as I am not interested in them. Don't ask me to place an order before you show me demo video. Contact me only if you are willing to work on my terms. Don't waste my time otherwise. Please read this request carefully.
