Do you have any manual machine experience?
Reason for asking this is that if the answer is no, I guess that my suggestion would be to bite the bullet, hire someone and maybe look over his shoulder. There is a reason that the CNC trade is a 4 year full time apprenticeship. If you have experience with manual machine, you have the basics down, and now you can move on by doing a lot of forum reading and purchase some machining books.
