:) Ok that clears it up, although with dedicated servers it is harder to estimate how many individual servers a Support member can look after at one time because of the varying scripts, programs, security levels, OS's and much more that can make one server a nightmare while others with just basic set ups are a breeze to offer support for.

Where a reliable server with a basic set up can require very little support other more complicated and resource demanding servers can require much more. and you have to reason in the level of server admin experience the client has as well, if they have a high degree of admin knowledge there will be very little need for support, however if their level is low you can expect quite a few support calls to begin with.

So the answer to your question is, there is no standard amount of servers that a support staff can look after as there are too many variables that can arise and the staffs level of expertise will also play a significant role in the amount they can take on.

As you are just starting out it would be best to keep your staffing levels low and take on more staff as the need arises, if you have a good knowledge of server admin then there would be no need to employ more than one support staff member to take on the night shift (the hours you will need to catch up with some sleep as you probably wont get much to start of with ) and as your server base increases so will your need for support staff.
