Homebrew PCBs

Can somebody on this group give advise on "Small cnc router books and 
plans" to rout pcb boards and ocazionaly engrave a copper plate.
I would like the max size of the effective routing area to be like an 
A4 sheet.

This book should include all the areas on cnc routing. The 
mechanical, electronic, and software stuf.

I am good in metalwork and have a reasonable knoledge of electronics 
but very litle of programing.

Please, can someboddy help me?
