Hi, when you start off a post make sure you put a detailed description in.
Plus, when you say 'esc's', do you mean etc?
Is this an extension of another post? If so, it's maybe a good idea to put this on the end of that one, if you know what I mean.

I don;t think a lot of people know that ESC stands for a speed controller.
Like, just try and keep off abbreviations wherever possible please :)

sorry, well this is the link http://www.servocity.com/html/speed_controls.html (http://www.servocity.com/html/speed_controls.html), and well they stand for electronic speed controller.

You need an amp why?
-
so as Hal9000 says,
you haven't provided enough information to answer the question.
how many Amps does your "12-18 volt motor" draw?
you are looking for it's "stall current". if you cant find this info online then try measuring it's current draw with a multimeter with it connected to a battery as you try to to stop the motor rotating.
you will need a motor controller that can handle that may Amps at the voltage used.
note that the first 3 motor controllers on the link you posted are only rated up to 9.6Volts so won't really be much good with your motors.
dunk.
