Phil
You've got to remember that whatever you charge for a job, it's not your money (well, not all of it)
It has to go towards all the other costs associated with running your business and covering your household expenses.
Therefore the prices you charge must be based on some sort of calculation.
Have you worked out your business and household expenses based on last years trading ?
If so, you can forecast this years turnover based on the same figures - this will give you a breakeven figure.
You can then adjust your prices to allow for an operating profit.
Remember Phil, there are thousands of successful carpet cleaners operating in all parts of the country, just as there are thousands of carpet cleaners earning a living operating in all parts of the country.
Where you area based has nothing to do with running a successful business.
If thousands of people are doing it and doing it well, then the problem must be YOU !!
So, what can YOU do better, what can YOU change ?
Look at your figures over the weekend and take heed of the advise regarding your website - and definitely take Simon up on his offer.
Hope this helps, keep your chin up (and put your prices up

)
