Your Machine is very similar to my Tsugami chucker lathe that I am doing a conversion on.
Since all of the hard work is done such as motor mounts and ball screws it shouldn't be to tough for you to do it yourself or for a local company to do it for you.
It is a shame you don't live closer as it is a bit of a drive from Kansas to CT.

Out of curiosity, whay is your budget?
I plan on doing my turret also and am looking for some good ideas. I have a few floating around in my head but more are welcome.
