"Based on our experience, skills and expertise that we bring, this is our best estimate. Be advised that an estimate is not just writing the code but includes work for various stages including discussions, proposals, meetings, design, development, testing, user acceptance testing, fixes after testing and more other stages. Would you want me to give you a breakdown of those stages as we want to make it easy for you to understand the estimate" Never let someone tell you your estimate is too much. If it,s too much let them do it themselves.
