Estimate of IT staffing costs for schools?

Hi,

I work for a small independent school and want to make the case to the bursar for some more IT staff hours. The trouble is that I have no idea what, on average, schools are paying for IT provision, in particular staffing costs.

I appreciate that this may be a very difficult, even impossible, thing to calculate due to the many different ways in which schools manage their IT provision. But can we come up with an approximate range, expressed 'per pupil', for IT staffing costs in schools?

Thanks, Ian.
