I find most who set up rarely understand how much outlay is needed in the advertising area, sure after a few years you don't need to advertise at all especially if it's ch installs and everything works off recommendation. You will be looking at spending £500 -800 a month on advertising alone if you are in a big city on start up , there is so much competition it is not even funny, forget the first page of google if you are not at the top you will get nothing . There is a lot i speak to saying they are dry for work and when I ask how much they spend on ads they say £100 a month and oh i have been out flyering and not had anything from it ! I know you wont , then this just makes them think oh i'll just drop my price and do it for less because they grasping for work. Fact is if you are looking to pull in over 3k a month then advertise like crazy. I think there was a day when you could just get a yellow pages add for a grand and thats enough , nowadays everyone is online or people find you from the craziest of places, had a job two days ago from a flyer I handed out in 2006!
