Are you sure you lost the work to cleaners charging LESS than you ?
When you decide to go full time you will need a lot of those jobs at those prices to run a business and a home.
Just as certain potential clients will be put off by high prices, so will others be put off by low prices.
You need to start as you mean to go on.
Without being too nosey, have you actually sat down and worked out how much it will cost per annum to run the business and your home and put money aside for tax, servicing, equipment upgrades etc;etc;
Only when you know those figures can you decide what you will charge for your services, not what everyone else charges.
And please don't give me the old line of "people round here won't pay those sort of prices". There are guys up and down the country charging decent prices and running successful businesses.
However, as your prices go up, sometimes your potential clients go down. Conversely you need less of them to earn the same money.
I actively set out to market to a niche area as I have no desire at my age to do 4-5 jobs a day.
As I said before, start as you mean to go on, or the more desperate you get, the lower your prices will fall and you will find it hard to raise them later for repeat clients.
