Sometimes price is agreed on quickly, the the actual work begins, and you hear about the layers of paperwork that might need to be done, CEO is on vacation, and has to sign off blah blah blah, like everyone said above every scenario is different, you have asked a question that has no answer. It is absurd to even try to answer it.
It is kind of like asking us to valuate a domain that is not named, just knowing it is valuable.
