Cloaker with a free trial

Hey, recently I've been getting into cloaking and interested in promoting offers cloaked. But at first I want to test the waters with a free trial, anyone got any suggestions? I've got the budget for a cloaker but I figured It's better to at first know what you are doing at least to an extent.

I doubt you are going to find trial of working cloaker. But you can always search cloaking scripts or trial google to test things.
