Is merging a debt consolidation loan with a car loan possible?

I am 20 yrs old and in 25k of bad debt. I am in process of starting my own dogwalking service after working 2 years for an established dog walking company. i know exactly what to do and 100% confident i will succeed. with that being said, my plan is to get a total loan of 58k to consolidate my debt and buy a new car. my mother has offered to co- sign on the loan and make my first 2 payments while i build my client list. dog walking is a very lucrative business, i've done it and have seen the kind of money that comes in. i know i can pay this loan in 2 yrs since i don't pay rent nor pay many bills except for my cell phone and gym membership. My mother and i are planning to speak with Bank of America. Is this loan possible?? what are some good tips of advice????
