DH works in IT. He has done some work on the side but no major projects. An acquaintance is opening a small office- 5-6 employees- and is hiring DH as an IT consultant. DH does have an hourly rate, but for something like this would give a project cost. Does anyone have any more specific suggestions as to what this would cost than 'multiply your his hourly rate times the number of hours you think it will take.'?
