3D Modeling of Single Shirt

Information for the business: 3D Clothes Modelling
Design details: Hello, I require a 3D shirt model with seperated collars, sleeves, fittings, buttons (I need to be able to apply different textures to each of the seperate shirt component). If possible, please seperate the components into different files.

Model should be in .obj file format, and I need to be able to map any type of basic texture fabric (stripes, squares etc.) to the shirt components.

The shirt model should look something like http://www.tailor4less.com/en-us/men/custom-dress-shirts/configure. Don't create an exact replica, do vary it a little!

I'm not very familiar with 3D modelling/rendering, but I'll need shadows as well. So all the necessary normal/texture/vertice data should be fully included in the .obj files.

Also, please provide me a screenshot of the 3D model with your basic fabric (or one of my choice) once the job is done. Thanks!
