Totally agree with this too much lower prices around
Rubbish, it depends massively where you live.
Try charging ?100 for 30 minutes in most of Scotland, the NE and some of the Midlands, you?d be laughed out of the door.
If you are fortunate enough to live in some parts of London or the SE then its possible. Even then there is so much competition and only a relative minority of guys who are willing to pay this amount, It is most definately not the norm.
