My guess is you have the answer on a per shift bases: One bright admin 
per shift. I would bet you will also get plenty of help from the user 
base, existing and future. As you already know, the volunteers from 
your users may be your best pool of advanced technical help and future 
worker bees.

One good lead technician can solve a world of problems. Several 
uninformed or uninterested technicians may never get anything done and 
downtime may suffer.

Budget for three or four spots and give most of it to that two really 
good techies ...
