Hi Robbo,
What type of work is it, domestic, commercial, Industrial? I know this may sound daft but take into account the customer and work,
is the work clean and easy, or working in a sewer.
is it working for a blue chip company that is racking in money or is it a old couple that have a black and white telly, (but be careful the old couple may be loaded lol)

Have you done work for them before? if so ask have they ever had problems with your work in the past I guess if you have then they haven't other wise they would not be asking you back. everyone is trying to cut costs thus contractors are being pushed to low costs. If you feel this guy is taking the pi** then walk away there is no point in working your guts out and not making any money for you and your family, that is why we work not for the fun of it ITS FOR THE MONEY TO LIVE THE LIFE WE WANT.
Any way up in sunny Scunny I would expect hourly rate of
