We offered to do them this Saturday for £100,... she nearly fainted !!!
I think she was looking to get them done for £50/£60 ish.
Ah well......Saturday lay in ! 
i would of said less if you didnt have to give them a good rub down,
i used to be a painter & decorator with a mate and some jobs can be a nightmare to quote on, i just done a out side of a thatched cottage in masonary paint and stained the windows in black then bitumen along the bottom, took 4 days and earnt me a grand,,,, nice work if you can get it,
i only take these jobs on for the end of each month when i have done all my monthly window cleaning, they dont come along that offten.
£50-£60 you would be better off staying in bed.... i would.
