I would step on EH toes. Their guide charges £250 for a days walk.
I prefer to swop info with others and finish in the pub.
if I don't charge I can always go to the pub on me own if they piss me off :0)
The "What colour is the 3 o'clock layline to Egypt?"brigade I leave to (Half) Astral Tours.
I'm a househusband so I'm available all the time.
Let me know when your coming and I'll email you my tel#
