@thisusernameismine No it's a cheek to expect services free - or even cut price - from a friend/acquaintance etc... As has been said, this is their livelihood.
DH has a job that people think he should do for free for them, and when he gives them his rates, they are insulted by it, and say 'never mind then.'
It's bloody cheeky, and I would never do it. Our older DC charges for their services too and we don't even expect THEM to give it to us free or cut price. They have both offered it for free, but we refuse and pay full price.
My cousin's DP is a taxi driver, and he took us to the airport last summer (30 miles,) and it was £35. He said '£15 will do. Family and all that,'
We said no way and handed him £40. He told my cousin he was shocked because the rest of the family, and most people he knows expect lifts for free, even though these 'lifts' are his livelihood!
Also, my friend's son is in a band, and it's shocking the amount of people who want them to perform for FREE, and say 'it's great exposure!' 'Exposure don't pay the fucking bills mate! 
People saying 'it's only a few hours of her time' are CFs of the highest order! 
Even saying 'she should do it for a discounted price - coz mates rates and all that' are have got a bloody nerve too.
Pay your mate and stop being a tightwad. She may offer you a small discount (like 10 or 15%,) but don't ask her FGS.
As a few pps have said though, seeing a friend as a 'life coach' is not a good idea anyway.
