Distance Counseling with Eluminate, Skype, phone, or text

I have considered distance counseling as a service I would offer, should I ever own a career counseling business.  I have thought of using Skype or the telephone as part of distance counseling, and also email for some things.  I have never considered using text or Eluminate until we tried it for class.  Texting could be good for quick questions or if someone can't reach me by phone.  It would not be as beneficial for counseling and/or for beginning sessions or the usual 50 minute sessions.  In person is definitely my favorite, but I could see myself using Skype and Eluminate.  I would want to know more about Eluminate and have some sort of tutorial to send my client if we were going to use that method.
