Already a college grad - what are my chances

I’m 27 years old, based in NJ and have already completed one Bachelor’s of Science in Business Administration (2.5 - DeVry) back in 2010 and have been working in sales for 4 years. I am looking to put myself in a position to get accepted into a top Law School. I am already aware that with this GPA, I would not get accepted into any good law schools. I am also aware of the LSAT and letters of recommendation requirements. I am also aware that DeVry is not considered to be a real school by many.

Does anyone know what is the best option for me? In my opinion, I’d definitely need to complete another undergraduate degree with a much better GPA and would also have to take part in relevant groups and/or committees this time around.

I am a little late on pursuing this but I just can’t go through life being a sales executive. I feel like I have a higher purpose than to just work in some dead end industry & job. I want to truly want to achieve this goal. I am willing to work as hard as I have to.

Based on the information given above:

What good schools can I possibly get admittance in? I’m open to any good schools on the east coast.
Will any of my previously acquired credits transfer?
Realistically speaking, how long will the whole process take me?
