Car and Bigger Home Fund

I am trying to raise money so that I can move my family into a larger home. I am also needing money to buy a bigger vehicle or fix my small car. I have a total of 3 children who live in the home, with 2 additional children in the summer. I would like for my children to be able to have a little space, with out feeling too cramped up. My car is small and pretty much on it's last leg. My car was bought used and had some damages to it. It has since had further damage including a broken windshield, catalytic converter broke loose from the exaust manifold. Upon closer inspection its been found that it had previously been welded together. In order to fix all the damages it will cost a considerable amount. I have a part time job that just barely covers my bills. Any help will be greatly appreciated!
