My first question to you would be is, do you have the manpower to change 800 sub-panels and the 30 meter banks?An apartment complex I have been working for has been purchased by a new owner. They have 800 sub-panels to replace and 30 meter banks to rebuild. The new owner ask me to be the Master Electrician on the job while his Electrical crew comes in and does the work. My job is to pull permits, inspect work and call for inspections. How do you charge for something like that?
