Easy, can do this as am trained in the counselling/seperation medical sector.
My experience of referring people to counselling/divorce/seperation - self help comes from the North American Market (Tampa Bay - Florida & Calgary - Canada).
Secondly, i don't do the mass-mailing, etc. i do the face to face talking and referring alone with phone calls and approaching ONLY those intersted in self-help and listening to advice on handling divorces/seperation and the issues that go along with it. Have done in the sort of matching those in need of such help to care providers as an aid/relief worker during the Tsunami in 2004, Hurricane Katrina/Rita, South Asia quake in 2005, Java quake in Indonesia and lately to mature students in college.
Numer of days depends again on your needs and which continents and audiences you're interested in attracting.
Let me know details of this assignment, and i'll be glad to help out.
cheers!
