The amount he is asking is fair

for acupuncture services

And you will not get results ( or lasting results) with just one treatment
This is not allopathic one visit and you're fixed medicine
It is a sublte energetic fix and he sounds legit
The gut and bowels are some times the culprit

If you cannot afford it
Is there an accupuncture school where you live?

I believe there are interns that give services in the 30 dollar range
Otherwise
I am sure there are other ways to skin a cat
