Security Audit : Fully Null a WordPress Theme

We are doing security audits for our themes. Here are my condition. I will supply you with theme. You need to null it so that anyone can use it without using any key codes, like one-click demo etc without key. You need to tell me what stuff, you changed. If it works, we will provide you with more projects. The price we mentioned is per theme. These are my conditions, if you agree, we can start now.
