Unity 3D Technical Artist (low experience)

I have Unity project, project has almost ready environment scenes and has 15 animated FBX. Task: To place ready animated FBX in almost ready scene. Probably need will alter position some objects in order to it don't obstruct the view from camera, or vice versa if the objects are poorly visible. For placed FBX you must assign exist material (can find by ready scenes). After that how you fully complete scene, will need make a video by script in project(just click one green button and a bit wait). Finally video will need compress to 10-20 Mb and send to me for checking. The amount of work is small, the complexity of the work is minimal, there will be enough a small experience in Unity. In attachment you can see how it should looks after setting up the scene.
