Peter, I am not trying to pile up on you here. I am sure you can tell from the responses that this is a sore subject for us all. However, I know that there are some very good elevator companies in the LA area. Some of them are on here and are reading this now. Perhaps you have not called the right company. I suspect they will all tell you the same thing, and it will come down to price and how quickly they can get it done. In any event, you have now raised this issue and there is a trail that the lawyers will trace back in the unfortunate event of an accident down the road.
I realize you were hoping for a great and easy solution but alas.......
