leaflets and leg work!!!
1.work out how many customers you want
2.leaflet leaflet then leaflet some more.
3.do a top class job for the customers you get from the leaflets. Do more than is expected of you.
4.watch the customers roll in.
hope this helps.
Point 3 is the most important.
You will get to a point where you will all the customers you want and will not have to keep repacing them if you get point 3 right.
websites are great if
1. you provide a terrible service and need to keep replacing customers
OR
2. you provide a great service and want as many customers as you can get, start employing people etc etc.
happy cleaning
