CNC rebuild ,matching drivers to motors

Hi
After having fustratingly tring to get my cnc machine to function over the last couple of years I've decieded to look into gutting the machine and replacing all the electronics except the spindle and motors. The router is a high spec industrial machine with a 900 x 800 cutting deck.
The motors are HY2000 3437 with encoder heads(RM21D-1000) on the X Y axis and a PH 268E2.3B with encoder head (5540-A06) on the Z. How do I match drivers ,power supplies etc to these motors.
Does anyone know where I can get hold of a simple to follow diagram showing the parts requiried and how to join up all the componets as I'm completely green to the subject.
Does anyone have any idea what sort ot cost would be involved using good quality components

Thanks,
Paul
