Unity 3D Modeller needed for mobile VR project

We need a reproduction of virus model on the picture attached for Unity. It will be used on a mobile VR application so it should be performant as mush as possible. - Virus shape must be spiral like (not straight like in the sample photo). Request shape will be given an FBX file. - All the roughness and deformations on the virus shell must be modelled as normal/height/detail maps. - The dot like particles inside virus shell should be a single mesh with lowest number of polygons and the small dot like particles should be made with normal/height/detail maps. - The former definition is same for the inner tube. It should be a pipe like shape and dots effects should be given with normal/height/detail maps. - Inside the inner tube there must be an additonal dna / rna like shape. We have a sample fbx for that but it's need to be cut/divided to fit inside of that. - The model will be used in an interactive app and all the seperate layers need to be selected with a controller. So they need to be seperate objects. - We are requesting an drop-in unity package, but also fbx / source file if we need to make further adjestments on the model file.
