I’m trying to figure out the best product(s) to use for my hobby project, which could develop into a business if I figure out how to do this efficiently.

I’m using Autodesk 123D Catch to transform photos into a 3D mesh of a person’s face.
I then want to turn that into a mold that can be used to make chocolate copies of the face.

Problems:
- 123D Catch doesn’t provide enough detail around eyes, mouth, nose.  So I’m exporting an .obj file to Autodesk Mudbox to fine tune the face.  But on import I get error messages about incomplete UV’s, or vertexes or faces so I wind up sculpting on a blank face which makes it hard to match features to the photos.  Getting hair done is also a problem.
- After tuning, I then need to select only the portion of the bust that I need, add a base to it, and give the mesh some thickness so it can be 3D-printed.  I haven’t found the right program to do that.
- I’ve played with Maya and 3ds Max and Blender but find them too complicated.  Maya supposedly could solve the problems I get importing into Mudbox, but I haven’t figured out how.

So what I need to know is what product(s) should I use ?  Is there one that will do everything I need, or do I need a combination of products ?
