One thing I would suggest is to go in to the next meeting with him armed to the teeth with information on how much it is going to cost to actually get the total value out of the machines...I have found when dealing with a lot of clients is that they do not seem to understand that time is money and the more time we have to spend tearing stuff down the more it is going to cost us. That means less of the total is going to be profit. Normally when I lay that out for clients like that they seem to let their guard down a little bit when it comes to the price.

Anyway, nice one Olddude, looks like it could make you a fortune!
