You might consider contacting a Formula 1 team; McLaren, Ferrari, Renault or even Red Bull. All these top teams have their own wind tunnels and design and build their own "chassis" from the ground up.

Their aerodynamicists are also heavily invested in CFD and the designers all have aerospace backgrounds.

A yearly budget of $200-250MM USD is typical of these teams.

Here's the McLaren website if this idea seems like an avenue you might wish to persue "https://www.mclaren.com/#"
