I'm 30, wife, daughter and probably another coming next year, work 50hrs a week including every other weekend, for about £20k a year before tax, driving job, nice house with a not so nice mortgage
Thanks again.
the alarm bell in my head went off with this
the family and "not so nice mortgage" , i guess that means its a fair sized 1
as tosh said, do not do anything rash
i would start off with building a small round, get out door knocking, you say you can work 3 days a week doing your job, well that leave you will another 2 or 3 days a week to work as a window cleaner, once you get your 3 days full, you can for a while let your work run over a little, for example, if you say you will be around every 6 weeks, stretch the freq of cleans to 7 weeks ( the customer will not notice and you can then gain the extra work, you will then be approaching 4 days window cleaning work a week, that in my opinion if done right it enough for you to leave your other job and just do WCing full time ( at 4 days a week at 100 - 150 quid you will be on your way to having the same money)
this is the way i would go, you can see if its all what its cracked up to be, even at 2 or 3 days a week you will realise if its for you or not, you will have to work hard for the next 2 years building up a round to work 3 / 4 days a week ( AND ) you will be doing your job that you do now , on the plus side you will have extra money coming in , which if i was you, i would put into a bank account and leave it for a "fall back fund" when you leave your old job ( you will have a little bit of a slush fund )
you could on the other hand, save like mad and pay a "door knocking company " or look to buy a round, then you can jump straight into a 3 day week, whilst still keeping your old job
i would be very wary of just packing your job in and starting up, its a long slog and you have other people to think about
