a good service should take about 2 hours if you charge this at 35.oo an hour is 70.00 service items spark plugs approx 3 each air filter approx 8 oil filter 6 oil approx 15 to 20 depending quality and grade. additional items would be fuel filter pollen filter general top up fluids. so to have an mot and service your getting an mot and the oil and filter changed under bonnet levels topped up.
good luck
