Write a User Acceptance Test (UAT) Test script for basic Magento E-commerce project

I will need someone who has written User Acceptance Test (UAT) script for Magento ecommerce project to prepare a test script for me. This script will comprise 2 parts : (1) Test script for end users guiding them how to test E-Commerce website to view; add; order; pay for a product. (2) Test script for admin, guiding them how to test add/manage/delete products and manage the content eg. banner, static page. This should be an easy task to someone who has prepared UAT before. I am most willing to agree to using duplicates of what have been done before. I don't need originality as long as the script is helpful enough to use.
