That is a good question personally i would first start my recruiting from the following:
1 Family.
2 Friends
3 Close Acquaintances
After i have recruited from all of the above,which is my warm market i would focus on other areas that produces a lot of human traffic such as:
1 Laundry Mat
2 Churches
3 Grocery Store
4 Malls
Families are among the first we would want to approach with the offer of being your recruit as most family is always willing to help.Also friends and even some close acquaintances.
When seeking a good candidate to recruit,we must know all the facts before we approach such person or persons,and make sure the picture that is painted by you to them is one that is hard to resist.
