On second thought,
Charge them $250 to tear out the whole deck, if you know the basics it should only take 2-3 hours to remove Everything and then you have maybe $50 in a Landfill trip (included in $250). Then you can lay a nice rectangular patio and have 2 or 3 wooden steps come down from the back door.
It saves them hours of sanding the deck(which they probably weren't going to do anyway. Plus the $50 worth of paint.
Save the old steps that way you have an outline to use incase you don't know how to make steps.
There is an Old Blue Chair for each and every one of us, we just have to find it.
