Look at it another way. What is your time worth and how much effort do they want put into each mini. I am in the ship repair business and do estimations for repairs all the time. There is a huge difference between a functional job and a rolls royce job. I would work it out based on how much time they want you to spend doing it. And whatever you do svart don't undercharge. Your work is genius. You might be able to do some functional gs work on a squad of csms in a couple of hours. On the other hand one of your current oblits would take considerably longer.
