It's unfair to name names Nathaneal but a very good friend of yours posted soon after switching that he's had his best day ever on about day nine (i can remember the figure), and he had been window cleaning for nine years trad before that.
When contrasts are as stark as that it should be pretty obvious which is the way forward in a business sense. I -more or less- started in WFP and have played what Graham Taylor used to call route one football ever since, I bought a van when I had a customer base of only thirty. My wife told me how stupid this was at the time.However I believe that now I am on par with any single operator on here and have leap frogged many.
As Ewan says there are many forms of investment including time and study. There have been several threads on here about employment and expansion. Many have employed and retreated saying it is a nightmare, it has worked for a few, but there is a period of expansion where you are worse off than if you had remained a single operator.Ian Ferguson came up with a brilliant and elegant solution to this in the form of franchising.
However, if you want to remain a single operator, but earn the maximum amount of money (as a business) then your only real option is investment. This need not always mean money, I note your excellent hot system and accompianing logo so that you have packaged yourself pretty well, but you are one in a hundred Nathaneal, and on the ninety ninth percentile it's a wonder you can breath up there.
For the majority, they can either learn from the forum, or they can spend, or they can be something in between.
I've got a hot system, i've got an electric reel, but I still think an expensive Ionics system is a very good investment.
