Not an agency
I understand that you want a 3d simulation app using Unity. I will be honest, I have worked mostly with 2d but I know Unity well, and have worked with 3d as well. Plus, I am an extraordinary programmer and problem solver, and your project seems interesting to me. I assure you that if you select me for the job, you won't regret it. ?
Please share more details in chat so we can discuss this further.
Thanks,
Tanzil
