Help to build a fast workflow "External 3d package to Unity"

Hi!

My name is Daniele, I'm an Italian freelancer for 3D Architectural Visualization.
Please take a look to this demo I've realized with 3dsmax/Vray and Unity:

It seems to me the result is good (considering also that I'm new in Unity).
But I can't yet "sell" the product because of the workflow to realize it is stil "slow" and ungainly.

To make it strong I need someone good in scripting unity knowledge which could help me to solve and discuss the different "problems" I've found along the way.

At the end I can easily record a tutorial and share it with no problems, "Packtpub" did one very very good regarding Unity and Architectural, but for me not yet enough if the target is more realism as possible and considering also the new unity 5 shader.

So, I hope someone could help me, or better, could help the community of 3D Architectural Visualizer
Good job!
