18 no credit two jobs and babysit...I need a loan for a car and a laptop for starting college in feb.?

I have only worked at one job for 3 months and the other for a month but getting my first checks I bring home about 800 monthly after taxes plus I baby sit and get an extra 100 a month. I worked at my last job for a year and a half but I have no co-signer or nor have I had a job for a year or more. I dont pay anything because I live with my mom. She has limes disease and recently was diagnosed with bone cancer so the only thing I ever have to do for her is clean up after my siblings and run around in HER car that she also needs so it gets really bad because we have to be stranded for hours at a time sometimes.I need a loan for $5000 and I plan to pay it back in 36-48 months... does anyone know anyone that can help me?
