Does any one know where I can get a loan to buy a used car,without having a job or any credit, or a co-signer?

See, the thing is I have a son and he goes to day care, and I go to school, but I dont have a car, to get me and him around, and I need money to buy a car, but I need a job to get money, but I need a car to keep a job, so what do I do?
