Hi I'm having a career change just now and looking at a few options of starting my own business, Window cleaning is one I'm doing research on and the only thing I was wary about was going up ladders (bad experience decorating ) I know the basics of starting up a business and ive read about marketing etc on here but I need help on what equipment i will need. I'm unsure whether to start with a backpack and work up or just get the trolly unit. What would be best to start with? I don't want to go out and spend a few thousand and not use most of it. Any help would be great. Thanks.
