Its always heartening to learn of somebody using his initiative to make life better and it seems you have done just that.Its also sensible to plan for the future and you seem to be doing that too.Before committing cash to a machine would it be worth spending some time learning to use the software that will be a necessary part of the process?The days of sitting in front of a machine with a print and a calculator and typing in G code are over for most of us-and a good thing too.Even conversational programming is unlikely to keep pace with a competent operator and a very basic CAM program (yes I expect a reply from an indignant conversational programmer and he may be right if only basic parts come his way) and a basic piece of software doesn't have to cost much or even anything.I would advocate learning some software and paying close attention to the simulations so that when you look at a component you can be confident of actually producing it instead of hoping it turns out OK.A week or two exploring the possibilities and maybe looking for a machine should focus your attention to the features you will benefit from.
Then when you part with the money for the machine you will be in a position to start producing parts. Unless there are confidentiality issues a few nicely finished parts photographed well and on a website will alert people to your extended capabilities and who knows what might turn up at your inbox.Good luck.
