It doesn't cost much to get started. A backpack, a cheap pole with brush, a couple of plastic containers and water from spotless.
I wonder how much modern radio advertising influences people in general.
I'm thinking of the arena of driving instructors. In just 8 weeks, be your own boss, work when you want to, earn a good wage, etc. No advert says anything about customers or the car needed to succeed, or that a driving instructor has to work to his customer's timetable, not his.
On the outside, our job is seen as an easy one that any body can do, made so much easier by not having to use ladders.
We've seen many new starters come and go over the years. In that time I've lost a hand full of jobs to new starters under cutting my prices, but most disappear after a few months.
I've even had one asking me to give him some of my customers.
It nice to occasionally see one who has succeeded. I do make a point of talking to a cleaner who maybe is cleaning a few houses away from myself. Some talk, some don't.
