I see some of the above input and also some valid points i see the average price from asking people was between £8 and £10 a month and some even had to direct debit it. i'm also thinking it's not a great idea also.
Tbh i just wanna make some cash during the school time were i have nothing to do there is more window cleaners than you can shake a stick at. Just basically want to do some manual kind of work instead of driving a bus part time it's an un healthy occupation and hopefully find something that will give me an oppertunity to go self employed i used to do decorating but to be honest when there was work it's good but the dry spells killed me and forced me into bus driving lol
