Help With Pricing Please!

I have been asked to give a price for a local primary school (no current window cleaning)

Seperate quotes for

1. outside only, once a year

2. inside and outside once a year

3. inside and outside twice a year

Pricing this is blowing my mind, any advice would be most welcome.

Theres probably about 100 windows, nothing too big and 90% ground floor.

Thanks

the best I can do with out looking at job is £1 a window

£100

£300

£200

Thanks chaps.

What do you think is about right £20/30 an hour?

And would you charge slightly higher for inside?

Thanks
