Hi There!
I read your game scenario.
I have experience developing an online multiplayer vehicle combat style game on Android.
In my portfolio you can see few shots from inside the game.
Therefore, I have a lot of experience in making this type of game and I can give you advice and even instructions for making this type of game and share all my experiences with you.
In addition I have to mention that I am a multi-tasking game developer with both Blender 3D modeling and Unity programming knowledge, so if you want to deal with 3D models in your game I can give more advise about that too.
Hope to be working with you!
Best Regards
