I actually think it depends on whether it is a hobby job Richard, or your full time employment. I would not be able to afford to charge £6 per hour because of my overheads, ie insurance, tool depreciation, fuel expenses etc. I work for an elderly couple a few doors away and I charge them just £12 an hour as I don't have to drive, but I still have to be insured and my tools still take a bashing. You do have to be careful, people will happily plead poverty to get the job done cheaper, everyone wants something for nothing.Regarding insurance, I'm sure a lot of hobby gardeners don't have it and work away in other peoples gardens, but if you break a window, one of their tools, cut through a power line or damage an expensive plant, you will be expected to pay for the repairs, also, if you injure yourself at work and cannot work, you will be loosing income. It might never happen to you, but it probably will.
I bless my digi camera and laptop PC when I'm doing really neglected gardens..... slide-show pics of the before/during & ta-da! AFTER are a big hit (and, incidentally) another money earner. Didn't plan it that way, honest :o ;D but a print out album has been requested a few times - and I'm there to oblige ;) I use Kodak atm....
