Dave has done really well these last four years, in fact since he went WFP. I really admire the guy, he bought more work, took on an employee, and has never looked back.
They say behind every successful man there's a good women, and Dave has posted in the past about how big a contribution his Mrs has made to his business.
The more free publicity comes his way, the more work he will get from it.
I probably won't be here, if he ever gets round to writing his memoirs, but if he ever does it would make fascinating reading to all wannabe window cleaners.
Good luck to you Dave, I would really love to know how you got that rocket up your backside, and if they still have any left, I want one. Dai
