I got feedback from Bill Morelli at UpNorthAviation.com. He is great! He couldn't read my files, but sent me back my layout the same day (today). I was pretty happy with the layout.
I finished up the side panels. I am going to ship them to him too so the holes are precisely located.
He says he will basically ship back the next day.
He is on the other side of the country, so the panel will spend 10 days on a truck. But it isn't critical path - I have lots of other stuff to do.
