I have been watching this topic carefully, Bulk SMS biz is great especially if you have contacts... am into this biz since January 09 and am very happy with it cos i have contact and am making money, many of my friends dropped and keep telling me that they dont have contact, i keep telling them they are only lazy about it.
one of the greatest problem people encounter in this bizness is getting contact (phone numbers), but since our Oga (Ken) himself have bring a solution down for us, i believe we shall grow here, i have ways of sourcing for numbers ma self in my locality or state involve, but really its a tedious one. but i will go with Guru Ken to learn this secret.
Also please you can target companies (do ur homework bfor going to any company) cos a word from a staff or anyone in the company can discourage you completely from this biz.(it happen to my friends).
Bless u all.
