Even then, what you will end up with is the manuscript of a monograph, not the finished monograph itself. If you get the quality publisher your study deserves, then they will subject it to severe scrutiny. One proof follows another till finally the finished text is set. This can be an exhausting process and not every publisher will be the best one to help you accomplish this task. Let's be honest from the beginning and say, there is no right publisher but it is likely that for you one or two will be more suitable than others.
All publishers have their strengths and weaknesses.
Your task is to find the one best suited to you. However, even though this publisher may have their flaws, for the sake of simplicity I will call this publisher the 'right' one. Finding the right publisher is simpler than many people think. If you know your subject, you should be the person who knows best. Knowing your intended readership, you should have a good idea as to who publishes books for them.
