Animate with a walk through a realistic movie from 3d model

Job ID: 33190207

Budget: $250 – $750 USD

We have a 3d model that is a replica to a historical site over a lake. It needs to be animated and to have old weary textures and materials.
The 3d model can be provided in sketch-up or 3ds max.
I want you to tell me how long will this take?
How much will it cost?
To what extent will it be realistic?
an example to how you'll animate it?

Down below I'll add a rendered photo to the work that needs animation (you'll need to change materials to make it more realistic)

Kindly Add examples from your past work for me to see.
Thank you!
