When i started, 5 years ago, it was a case of, if i start up, it would HAVE to work!
Just come out of bankruptcy, a single dad with a son in private school, loads of overheads, so giving up wasnt an option!!
I just went for it and it worked out well for me. People said to me "not enough windows to go round"
Not a proper business, so on and so forth!!
If you want it to work, it will...simples!! As far as im concerned, i would never turn back the clock, never change what im doing, and this tio me is the most flexible business you could ever have.
Saying that....its bloody hard work...the work doesnt come to you, you have to get out there EVERY SINGLE DAY knocking on doors, 7 days a week, until you get enough to live on.
Then you need you build on that. Its not for everyone, you need to constantly be getting your name out there.
Make sure your family is behind you, cos with someone behind you giving negatives all the time, its a struggle!!
Good luck though in what you do

Just want to add.......ive had about 7 fellas come out with me to see if its for them, 1 is still a window cleaner. Not wanting to put you off, but he was the one who worked HARD!!!
