Hi Chinney,
November and December are usually the busiest months of the year, Jan, and feb are the quietest.
Only time will make you so busy that you are booked up weeks in advance, (I have been in business for 15 years now).
All of the previous customers and recommendations just sort of build up until you don’t have any need for advertising

But when I started up I found that a leaflet drop worked
VERY well at this time of year. I remember doing my first £1000 week in my first Christmas trading period (15 years ago !),
all of that trade came from a leaflet drop.
Its very simple, when not cleaning carpets distribute leaflets

You can not fail at this time of year, its guaranteed

Chris
