Need urgent help with car repairs

Hi my name is Mitch and usually I would not try this .
I am a house painter in Brisbane
2 years ago I went into business with a former work friend . It didn't go well and I have never recovered from it financially.
2 days ago my car broke down I use this car to get to work witch i need to carry tools paint ect.
I work for my self but only make enough money to pay the rent and bills i do have children so they are my first priority . I am to nice and help people out with paint work that doesn't break the bank . But now I have found myself needing help .
I have a huge list of mechanical work that needs done to my car . Feeling so lost and broken
