Am I wrong in giving them **** and telling them I can't do this by myself and if you don't help get the plane out of my shop.

I would do the same, in fact I have, always made a point to be clear that I would be happy to help and teach, but in no way am I going to do it for them, not even when they offered to pay me for my time, that was insulting in my mind.
