Phil,
If you are serious about this, go to your local shop you use and ask point blank, what's it going to run to do "X"? Asking a bunch of people that don't live in your area is not really going to assist you in making a choice or a realistic cost estimate. I do know that some of the quoted machining costs are a bit lower than where I live. Every area has a prevailing rate and it's not consistent with the cost of living. Some So Cal places are less expensive than small town prices.
If you cut corners, you could possibly build something for 2K.
