How many customers do you have??? for two years.
Are your existing customers happy with the service?
Are you getting recommendations from existing customers.
Your quality of service should be your best advertisement and you should be getting recommendations regularly if all is well.
We get no end of extra work, never leaflet, never advertise - all through recommendation.
I think we have about 600 customers at present and it is still growing, this is for 5 years of self employment, 120 per year.
Sometimes it feels like you aren't getting anywhere and then all of a sudden it all starts clicking into place.
If you are offering the customer what they want at the standard you and they are happy with just keep doing what you are doing
Good luck
