Lawn Care pricing

Hi
I'm a qualified greenkeeper and Gardener. I'm Looking for opinions on how much people would pay or think is reasonable for a professional lawn care package throughout the year (March to Nov-approximate 38 weeks )

It would consist of the following.
•Grass and edges cut x 31
Cut Fortnightly in March and April,Cut weekly through May to Sept,Cut fornightly Oct and a final cut in beginning of Nov.
•Mechanical spike aeration x 2
Once in Spring and once in autumn.benificial for compaction, drainage,root growth,nutrient uptake,Air flow ect ect ect.
• scarification x 2
Once in spring and once in late summer.benificial for removing moss and thatch,over seeding,thinning dense sward/grass.ect
• Moss control x 2
Spring and autumn.Two applications to remove or deter moss depending on the situation.
• Fertiliser application x 3
Once in Spring once in summer and once in Autumn.Tailored slow release fertiliser for the situation.
•Weed control
Twice annually.Pesticide application where necessary.eventually replaced with hand weeding as weeds reduce.

West of Scotland pricing.thought welcome from else where
So for all the above and a head turning lawn would you pay.....

Under 75m2 = £50 x 12 monthly payments(minimum)
100m2=£62.5 x 12 monthly payments
200m2=£85 x 12 monthly payments
Ect
Reasonable,cheap,expensive?? What's your thoughts?
Thanks
