Now you said you staying Colin, what you got to do is make it work.
I am sure Nick gave you some very good tips, as you know not only does he sell good products but he is also a hands on successful carpet cleaner.
Have you tried door knocking - dressed in your work outfit if its smart, and deliver your leaflets personally to the householder. Twilight hours best for this, when people are at home. I reckon you will get some good success.
And things are not as bad for everyone. I just had my best month since Nov 09, and before that Dec 08. Way up on last June. Job ticket dipped below £100 (£97.50) but there customers out there.
I think Derek also said his June was a good one as well.
Go and get it.
