Hi Michael,
You do not say from your post its "only a few hours per day" and to be fair judging from your reply " at the end of the day its classed as an unskilled job dick head people " I think your attitude to your employees would not bring the best out of them!
How you expect to get a good conscientious worker is beyond me, I agree £30 per hour is not the norm , but a fair wage would surly benefit you in the long term.
Your opinion of an employee really should change
. if I was categorised as an unskilled dick head working for you, I would soon be cleaning windows on my own on your patch, after all I would not need many of your custys to soon attain the £40.
I apologise if I sound blunt, but exploitation does not bode well with me.
Geoff.
ps. Spelling and grammar has never been a strong point of mine, but I would suggest you change Proffesional to Professional on you web pages.
