On rare occasions I am wrong
; however, my guess (and it is just a guess) is that you won't have much success here with a psychotherapy practice. Legally, you will need to take on many tasks to be considered "licensed to practice" here in Peru - that entails certifications, translations, and an entire process by a board of specialty to certify your training and credentials. Once complete, you can practice but if english is your only language, and though many of us expats are nuts
, I doubt you will find the revenue from a few expats suitable to cover the costs for an even remotely decent lifestyle.... this is just my personal opinion. I do wish you the best of luck however.
