When I first started I bought a small round off someone with 163 customers for twice the value of a clean. I've only got 3 of my original customers as the prices were not the best shall we say and not my preferred choice. Most of my work now is miles from where I started from. I wouldn't buy a round again as I would prefer to go out and doorknock in the areas I would want to work in. Wouldn't canvass council estates, rented accommodation, new estates or terrace houses. Just aim for self builds, semi's, detached and rural hamlets.
