That is way too broad of a question and is part of why we have private forums, to allow potential and current center owners to share ideas, thoughts and information. I spent 14 months, full time, researching the details to come up with the numbers we worked with, while they have shown to be pretty accurate, the questions that needed to be asked certainly could not be summed up into one question.
I found a very substantial amount of information in the iGames private areas that helped give me concepts, ideas, and numbers to help me develop my business plans.
Consider the honoray iGames membership, as suggested.
