The answer is none if you install it perfectly and never use it.
If you answered a or b, your system is the equivalent of a big brother contestant - unstable and in need of some attention. Day to day maintenance is vital to the successful smooth running of any system. Virtually all day to day problems can be fixed easily and inexpensively, but left to fester cause expensive system crashes.
So the right answer is one. Most companies have a big enough IT system to need help, but not enough to justify a full time IT Manager. tlp can provide one day a month maintenance support where your allocated technician will come in and do all of the jobs you can't do or haven't got round to. Problem solved.
