Baffling what "paperwork" they think they need to be on.

How about the simple obvious that the inputs to deliver the service/product have a base-line and market prices have, OBVIOUSLY, been at about as lean of operating profit margins as can be. 

I hope this helps you land on goals, then you can dive deeper into where.

I can see in that one pic that you could use a bit more artwork on the walls.

I have been working with investors in my area and partnering on deals for the last 4ish years.

The next option is to get the device (you can get on Amazon) that shows the meter for what one unit is pulling versus the other.
