i done the same spent 4 days pricing work 4 a 2 year contract, what a waste of time the council employee i went round with wasent sure which windows got cleaned & which dident then halfway through the last day they went home left me to it!, they said the windows were cleaned every mnth( as if half of them looked like they hadent been done in yrs)cos the previous window cleaner seems to hav got away with missing loads of windows, thats maybe why his price was cheaper.
iam not expensive by any means but cud not get any where near ther price,
