Student loans for transportation?

Okay so i'm going to be starting college (Tulsa Welding School) on Tuesday and I need reliable transportation since the only one i have right now is my brother and he won't be able to take me to school every day. I talked to the school's financial aid lady and I was able to get a 5k transportation and housing (basically I can do whatever i want with it, which I was planning on using for a car) loan with the original loan I had gotten to pay for the 7 months of the school's tuition. The problem with that is that the check takes 4-6 weeks to arrive so i'm gonna have to wait a month+ for it. So my question is if there's anywhere else I could apply that would give me a loan (not for tuition, i have that covered) to buy myself a car for school. I'm currently unemployed and have no credit so i'd like a loan where I could use my mom as a co-signer or if they don't check your credit which I highly doubt there are any out there that won't check your credit. And also one I won't have to start paying 'til 6 months after I graduate. So can somebody please help me out and give me some sites and info ? Thank you in advance
