Hi
The so called scumbags that you refer to, are using a technique called
Bait and Switch, which you may of heard of, as it got its name from the Motor industry in the US!!
If what you are saying is true in you area, then most probably your neighbourhood is looking for some one like you
I would surgest that you market yourself on the very point of being profesional, but your advertising can not be just one off's, because they don't work. You need to be consistent.
From what i am lead to believe, you are quite big on networking overthere.
Seek out some networking groups, as many as possible to promote your business, the B N I is one, and yes leaflet drops are a good way to get business but you have to do an awfull lot of them:(
The best of luck to you
Ian
