2 Get a corporate or engineering job, save lots of money through the stock market so you can have capital to start a business - this will teach you how to look at the paper end of a business.
3 CNC machines are very expensive thats why you need capital - buy one according to your needs there are lots of them. I assume your talking about cell phone cases when you say molding - So buy a Sherline under $1K so you can make a prototype - then you try to sell your prototype on amazon.com. No need in buying a $50K machine not including overhead such as building rental; Plus you will know if your idea will sell.
4 Expensive machines prevent much of piracy also the patent office is there if you got a really good idea to protect.
Chinese Machining is not very accurate - you get what you pay for. US always wins against them in accuracy in production
5 To start a half way decent cnc machine shop you need about 1 million dollars. This includes good used machines, rent, tooling, insurance, loan interest, legal fees, computers, permanent phone lines, software, guard dog, and etc...
As you can see its not a very cheap proposition - if you have family money to spend then thats the risk you are taking -
I myself work as an internal auditor for a fortune 15 company - so my salary is very good. I assuming my family business and turning it into a cnc machine shop in a 3 year plan. Part of the plan includes me coming up with $150K to buy machines - yes this is sucking up all my paychecks. My family already has 30K sqft - land and lot with the existing welding business which is been appraised at $4 million since it is in Houston proper. I already have customers in the pipeline since my family business is a major vendor for Landry's(publicly traded).
You may think your clever, you may well be- but I got a perfect score in Math and top 5% in English in SATs . I have a degree in business and computer science which I both use in my professional career - so I may be your peer intellectually. My point is you will need a lot of resources inspite of your clever self. But don't be discouraged - but you may need to think about this a little bit more.
