You could get most of that, but not all from a state school. You would need to add in other services, which come with their own costs. Could probably get it for less, but you are paying for the convenience of it being all in one place.
8.20am start - you would need to book breakfast club
senior teacher always waiting by the gate to greet each child by name - the headteacher at DD's state primary does this
writing, maths, phonics etc in his class of 12 children that has 1 teacher and part time TA - groups would be bigger in state, you could maybe hire a tutor for extra lessons outside school to compensate
No disruption - luck of the draw but far from garenteed
forest school once per week - DD's state school did this
Read with actual paper books! No tablets - plenty of schools do this
The teacher or TA reads with him most days - more likely to be a volunteer parent, plus you can listen to hin at home
sports 3x per week, including swimming, dance and PE, club until 4.30 every day, things like art or sports - you would need to look at out of school clubs and classes, my kids do all this but not at school
after school care til 5.35 if you want it - afterschool club would do this for additional charge
a lot of contact with the teacher - any emails I've sent have alway been replied to, but more likely to ask thing at pickup then email me
lots of outside space so the children help occasionally in the vegetable garden - depends on school, but plenty have this
good quality food, cooked on site - most state school lunch is terrible, but you could always send a packed lunch
school trips 3x year - about the same, but mostly to local national trust place or free museum.
