What many schools misunderstand is that the runningcost of a timetable is not a fixed quantity and can vary wildly based on the quality of the solution and how well trained the staff are that manage the ongoing timetable.
The downside, of course, is that full - service solutions tend to be costly over time — creating tours for 10 houses could run $ 3,000, assuming each house cost $ 300 — and you're at the mercy of the provider's timetable.
