A few things about the way Business Careers operates:
1) Job Placement is not free. Either you pay all or a portion of the placement fee or your eventual employer pays the fee. You are probably not going to get paid as much as if the employer didn't have to pay a finders fee. So, this really isn't free no matter how you look at it.
2) They seem to go by the "have you interview for everything and see if it sticks mentality." So, expect to have them call you with things that are not appropriate and do not meet your specifications.
I would suggest seeking help from your local Worksource. It's free, and they can give you just as good advice.
