I'm sorry to learn of your continuing problems. I gather you meant your new people estimate $900,000 to fix everything and that it involves undoing everything and starting fresh. It's a very tough pill to swallow but sometimes the only realistic thing to do is to cut your losses. Whether you want to start fresh depends on whether you have the money to do so in a COMFORTABLE MANNER and whether you have other priorities in your life. At the end of the day, there are costs to achieving anything in life. While other people may have their own views, you alone are the person to decide if the costs are worthwhile to you. Make sure you take time out for some R&R while you clean up this mess.
