Help With Project Needed - Guru Needed Please

I would like to add cnc capability to my lathe.

To be clear - I do not want to convert my lathe to cnc, I want to add a cnc router to it. I know what I would like, but have no idea on how to design it.
Even basic like motor type confuses me.

So I am looking for a mentor. Some one that I can email or even call to discuss my needs and aid in its design.

Basically I will need to have it travel left to right more or less 38",
in and out 2", and up and down 2". The parts I will be cutting at first are only tapers in wood. they will have several points of adjustment.

As by way of example - lets take a 1 inch wood dowel - cuts are as follows:
.75 for 1"
then
a taper of .01 over 5"
then
a taper of .025 over 5"
then
a taper of .05 over 5"
etc till the last 2" which will be a straight dowel.

I want to be able to mount this "TAPER ROUTER" behind the carriage so I can continue to use the lathe for other projects. It would also be nice to remove the entire assembly when not in use.

Is anyone interested?
