I remember when I started up - I canvassed my ahhhsss off, between 50 and 80 hours a week, then as the customers came in I cleaned them and continued to canvass. It was basically 12 hrs a day, 5 or 6 days a week.
As I got busier I had to change direction, I couldn't keep up so I took on my son, still working 60 hrs a week mix of cleaning and canvassing. As more and more commercial came in I sold off some domestic work as I knew I wanted to employ and prefer commercial for employing.
Allow yourself a year to build a half decent business, and I do mean, Half decent, but only if you work your butt off
