I found a really good YouTube person for 'hypnobirthing' (although I would actually just call it sensible breathing in labour!).
Its called 'The positive birth company'. I have to say after watching the videos I think that for most people these would be enough (perhaps with a cheap c.d from amazon to listen to as well) to get them through labour.
When I had my daughter years ago this was not really 'a thing', and I can see that it has become a really positive technique but it is also been branded and repackaged and sold to women who otherwise may have it in them to do it without having to spend. It's something we all have the capability to do I think.
A lot of what she says in these videos came naturally to me personally and I had a really positive labour with no tearing and only had pain relief (one shot of pethadine) after 10 hours (no gas or air either at all as it made me feel sick).
It just made sense not to scream and shout and panic I guess and I was very lucky that the labour ward had no one else in so had 3 midwives to guide me through when the pushing began.
These techniques she talks about in the YouTube videos was exactly what I did (the up breathing and the down breathing for both stages) and I was on my feet again a few hours post birth and back at home the same day. Not tearing again this time is obviously a priority, and I'm sure luck was also involved, and not having a huge baby (she was 7 pounds) too helped.
But the breathing through the contractions really helped me and actually kind of going to the 'mind palace' as Sherlock would say, was essential for me to remain focused and as calm as possible.
I managed a good 8 hours at home before going into hospital this way too, though I have been warned not to wait so long this time in case I have her on the kitchen floor 
I'll attach the link to the videos, I honestly think the courses, although for some people will help anxiety ect, are trying to sell you something you already have inside you. Though I understand 'accessing' this for some people is difficult and if you've got the money they do sound relaxing and informative.
For anyone else the online video's available combined with a c.d for labour could be enough
