Controling Arduino UNO/Analog Joystick "in" to Serial "out" to Sabertooh M.C.

Sabretooth 60/60,
Arduino Uno,
Apen Hall effect Joystick "X"_"Y" axis 0v-L, 2.5v-Mid,5v-H analog to Arduino UNO
Want to control, Qty 2 DC motors, One from "X" Axis and One from "Y" axis.
I will be using 2 XBEEs 900mhz for long distance wireless operation between Arduino UNO once I get this working.
Does anyone have a working sketch that would work for this set up?
Need to control each motor independently, centered position for both "x" and "y" axis would be stopped.
I am presently controlling these motors via same Joystick direct from "x" and "Y" using 5vdc from a Sabertooth 60/60, what I do is rotate Joystick 45 Deg so the "+" pattern is now an "X" pattern and mount it to a console
Now top of pattern "X" both "x" and "y" axis are now max forward speed and bottom of the "X" pattern for both "x" and "y" axis are full reverse
Joystick moved straight forward both motors drive forward, Joystick pulled straight back both motors drive straight reverse, any variation left or right steers unit in that direction
I have never tried this programing other than trying to find a program already written and uploading to Arduino, no luck yet, I have the XBEEs talking with each other, but need coding for both Arduinos transmit and receive ends
Willing to pay for some help if needed
Please advise, Thank You
