I've got several blogs on Trulia offering free advice on BPOs and how to get into company systems. The certificate from the school is just another one of those places to spend time and money. Very few companies care about this sort of thing unless you are "certified" by a class they approve, which most of the time happens to be owned by them for an additional moneymaker. The 2 year requirement is getting to be more common, but don't give up. Plenty of the good companies will take you on with less than 2 years experience.

Read some of my blogs on signing up, getting into the system is a simple process to get that 1st BPO.
