Sorry @apeo, only just seen your question! To clone a whole suite (or lab) would take us around 2-3 hours. That's with 3-4 drives, and 2 of us doing it. I'm not certain on how we charge labour, but I do believe when we do new installs of suites etc. it is usually charged at a set rate, based on the job. Most schools we service have a monthly contract with us, ranging from 4 hours a week (which is actually a surprisingly large amount of time to maintain some schools) to 2 hours a month (again, they cope (due to budgets I guess)!), to ad hoc support where we visit only when required. No two schools are the same infrastructure-wise or in the level of support they need, so we have to taylor it specifically to their needs! Hope that's cleared everything up for you!
