I'd just tell him to F**K OFF! and chuck things at him...but that's my inimitable style (not as Love and Light as I probably should be

You could try the website: shamanism.org
This will connect you with practising Shamans if you require this form of intervention -in New York, so it wouldn't have to necessarily be "Distance Work"
This may be what is known as an Intrusion
You would need a Shamanic Practitioner who can work with Intrusions.
