Cleaned a hotel for exterior for 35 quid and she wanted downstairs inside doing.. so i quoted 60 kwid she went up to her manager and came back down and she said thats fine Then she goes we would like you to clean all our hotel room windows. we have 28 rooms. so i said to her how would i go in to them whats the best time.. she goes we would give u a master key etc. So i quoted her 85 quid.. thats like 3 kwid per room so i think its good price ! plus its gonna be time consuming going in and out of the rooms.
