Ok, I have to ask how wise it is for you to be doing this. If you don't have equipment, capital, knowledge or experience in the field, what are you bringing to the market to keep your new venture afloat?
For machinery, what I would want to start out is a 4-axis mill and a lathe with live tooling (this allows you to perform milling operations on lathe parts). Cost is probably somewhere between 100k and 200k for the pair, depending on size and quality. You'll also need all the tooling for them, inspection equipment (a CMM would be good to have), and a variety of smaller manual tools - grinder, press, etc. It's not a cheap shop to equip.
If you have to hire a consultant to get this far, my advice is to find something else to do. Either start a business in a field you have a lot of expertise in, or go get a CNC certification from a local community college and go to work for a fabrication company for a couple years to build basic skills before you get into a quarter million dollars of debt.
