If you want to grow rapidly...................never say no!
I started my original cleaning business around 23 years ago, by accident, when walking around a new development in Glasgow.
I was looking at the landscaped areas with a view to offering a maintenance service, when approached by 4 people who asked what I was doing.
When I replied, they asked if I did cleaning as well, for some reason, I said yes and was on my way to my first contract, which had grown to 14 contracts within two years.
I learned very quickly, by talking, trying, listening, grafting.
