Hi!
I would love to work on this project with you. I can deliver end files, that can be used on iOs, Android, Mac, Web or/and Windows as I use Unity Pro with iOs and Android plugin. I already made something similar, but from the hi poly architectural model (Please check out Dubrovnik Airport, it's free on Apple store) and it was not walkable, becouse they wanted only the rotating outside 3D look.
As I am from Slovenia, I can also speak German. So you can also send me the instructions in German.
I placed a lower bid than my normal rate, as this is the first time I bid on Freelancer.
Thank you,
Matjaz
