This is why building trust by starting small and delivering exactly what you said you would for exactly the price you said is key. Clients and stakeholders alike will never cease the asking for more than you can reasonably deliver because they have absolutely no way of knowing how reasonable their request is. That is why pulling all nighters and heroics are so bad for developer / business relationships. They set a precedent for what is reasonable or possible. If the client or stakeholder never really can have the data necessary to fairly judge whether you are "holding out" or not then the only thing you can do is build personal trust by doing what you say you will, not a damn thing more, not a damn thing less.
