I think that if you are on an all day job, then a charge of £150 is pretty low, if I work from 8 till 5 I'll do more than that, I'd be pretty disappointed if I didn't top £200.
But if you are charging for 2 employees it becomes a different matter, for one thing you won't be paying them anything like that amount will you?
So £150 per man per day is I think about right, and if you are employing guys then they will need to be turning that over to cover all your costs, you've got to make money on them too of course...
As for individuals knocking out £750 per week, well, many on here will do that and above, but maybe not every week, those that do so are doing very well indeed.
But if you are going to charge for a full days work, then £150 is more than reasonable...even if you don't do it every day.
I've been hit with a wave of laziness today, finished at 2.30pm and have done £135, previous 2 days was somewhat above that figure (I'm not saying what though), and if the weather doesn't bugger me about it'll be above it tomorrow too...it could also be Friday if I wanted it to be, but I might want to surf another lazy wave
