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
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 ...
