Hi dossman71. Welcome to Psych Central. Sorry you can not find reasonbably priced ketamine treatment. Many insurance plans do not cover so it seems to be often private pay.
I know nothing about any of these places but I would ask your doctor if they thought ketamine treatment might help you.
Here are sites that may be worth exploring to see if they are legit and reasonable
