The Accountants

Something I have been wondering.
Seven fulltime Accountants
From those in the know out there
How much work would have to be about to come in for this many to be kept busy.
A Pro like MF surley wouldn't hire them if the work wasn't there.
After all it was in an ASX Ann.
But back to numbers can any Accountants out there give some clue as too say a practice with seven fulltime Acc.
How many types of processes or income would that many people be generating.
For the business minded. Would you hire seven full time Acc if the work wasn't there.
Would that make sense.
Would a good business person research or get feedback or just be out right told by clients that they want the service before hiring the seven full time Acc.
Thoughts???
