Medical virtual reality

Hi

I would like to hear the opinion from you guys about a VR project pricing.
It will be something to teach people how the cells in the human body works.

something like this: Flu Attack! How A Virus Invades Your Body | Krulwich Wonders | NPR - YouTube

What would be the budget??

In my mind ruffly I though like $25,000 to $40,000.

What do you guys think?
