Customize a bootkit for internal security testing of our environment

We have a private, internal software environment we wish to test security measures by testing a custom bootkit in said environment. We are looking for anybody to customize a relatively recent/modern bootkit for our environment. Disclaimer : This is not for PUBLIC use, we are not asking anyone to make malware. Anybody interested, please pm me with details of how you could develop a solution for this project eg what bootkit, variant etc.
