Hi,
I have been working in Unity since past two years!
Developing VR and AR apps in Unity is my specialty! You should first checkout the reviews on my profile given by my previous clients :)
Well, all objectives you have mentioned in description are feasible and I have worked on them, Important things are data, and server! We can fetch data directly from a server or we can use asset bundles!
Can you please contact me for further discussion ??
Thanks for your time :)
