Hiring a Person to test php Script

I am hiring a person from USA only to test a rewards script based on php and uses CPALead.com surveys. You don't need php knowledge but will have to complete 3 surveys from CPALead network on this script and wait for my confirmation if the script working successfully or not.
For this tasks I am paying $ 3 if the script don't works or $ 7 if the script is working. I require 2 people for this task as of now.
