Car Fire Leaves Keyba Stranded & Seeking Aid

Hello everyone. My name is Keyba. Yesterday July 1st around 11am my car caught on fire and blew up. On sunday 22nd I took my car to Walmart for an oil change. On Monday 23rd my car was smoking and leaking oil underneath and on the engine. I took it back to Walmart they cleaned the engine and said he will check the camera to see what happen. Then he said it's not leaking anymore. I leave and 3 or 4 min later it's back leaking oil and smoking. I turn around and go back to Walmart. The supervisor and the 3 other repair guys are checking my car. They still can't find out why my car is leaking when it wasn't leaking when I brought it in. I leave and go down the street to an auto mechanic shop he looks at it and tells me he thinks they over flowed it but he'll look at it tomorrow. So I leave and bring my car back to that same shop Tuesday June 24th. My car stayed at that shop being repaired while still paying for parts he thinks is the problem. Monday June 30th i pick up my car around 4pm put gas and take it home. Then yesterday July 1st went to walmart for groceries. Told my husband they car sounds funny and I smell smoke. We took the car for a drive around some corners and it starts smoking. My husband gets out to see and it catches on fire and blows up. I only had liability. So now I dont have a vehicle to get back and forth to work. Im trying to find a lawyer to help me with this case against walmart and the auto shop. But everyone doesn't deal with it. Then a couple said they need $3000 just to look into it. I need your help with getting another vehicle and a lawyer. Please. This isn't normally me. But a friend told me to try it. Thanks everyone.
