3D Model Texture Application

Description

I have purchased a 3D model from TurboSquid that includes multiple file formats (.max, .fbx, and .obj with .mtl), but am encountering issues with importing the model with its textures intact into PowerPoint, because PowerPoint only accepts .fbx or .obj, and neither of these have the textures.
I think I need somebody to apply the textures to the FBX.
Should be a very quick job for someone with the right software and skill set.
Just to be clear... I have purchased everything, I have all the textures, just need some help with getting things in the right format for PowerPoint.
