Hey Emma, I don't know heaps about hypnosis but I don't think you would need to be seen in person for it to work. The brain is a really powerful thing and lots of those relaxation CD's work!!
Back when I was in high school I had a tutor who advocated listening to tapes of the material before bed and lots of people swear by those hypnosis to cease smoking CDs. I agree that $40 is nothing in the grand scheme and at the very least you might sleep better!!
