From your posts, you appear to have little or no experience with CNC mills or CAD/CAM. It's very difficult to assist you with this when you have unrealistic specifications for yet to be imagined projects. If I can recommend a doable approach, buy a smaller (not hobbytype, if you have the money) 3 axis CNC vertical mill, a CAD/CAM package, and start your climb on the learning curve. You can always move up as needed.
