Well im just outside Bath, and 2 of us work, i do downstairs (im 6ft 3 and can reach windows without a pair of steps or pointer) and my mate does upstairs,
we earn about 100 quid a day, now on our own, we would be earning roughly 80 quid a day
its faster if there are 2 of you, you try and beat the other guy, and 1 has to carry the ladder, and the other the bucket and ladder stop
mainy will say, but the person downstairs has to wait for the guy upstairs, true, BUT i put the "we have cleaned your window" ticket and do the paperwork and take the money if they are home, thus i catch him up then
it works well, im happy with 100 quid a day, 300 for a 3 days week
