In my opinion the TO isn't familiar at all with quotas.

That is also my impression. Because for each quota, there is a specific end page where you can leave specific messages. No need to create a text display question. You can write your text as Quota message.

Because the way he wants to go about (if it is the case what you are saying, Joffm), then there are a couple of downsides to his approach:

1. If you want to "submit" a survey that is actually a screen out, it is counted as a completed survey in Limesurvey.
2. You would need to create conditions for all subsequent questions to hide them

@OP: I really think you should make yourself familiar with quotas and especially zero quotas, what they do, how they work. I think you will find that they are what you are looking for all along.
