The training costs £695-see here
http://www.hypnobirthing.co.uk/practiti ... ourse_costThen you have insurance, I think mine costs about £130.
I think the book and cd costs about £20 (when you buy it the cost is in dollars)
Room hire-if you need to hire a room, when I started I taught individually, I currently pay £25 for three hours.
Theres no area, I think in Nottingham there is about 4 or 5 of us, when I started I was the only person, but as theres more its more people advertising etc and theres more than enough work to go around

Clients are free to contact as many people as they want, choice is good, its gives a variety of class times etc.
You have to print out the handouts but that doesn't cost too much.
The renewall fee-$70, you don't pay a fee per client or percentage or anything.
Then any advertising you do etc.
Thats about it I think.
