I will single out two methods that is best for the beginner.
1. Word of Mouth (one on one): Tell family members, friends, colleagues and associates about sfi, explaining to them the benefit. This also include the use of social media like facebook, whatsapp, linkedin bbm and all the rest.
2. Email advert to contacts (please dont spam) tell them about this wonderful opportunity that you have signed up for and how it will be beneficial to them.
