Mechanic Job in Phoenix, Arizona

I am in real need of some help asap. My husband and I have been doing everything possible not to drive our car off a cliff. It is misfiring in all four cylinders at different times. Timing belt has not skipped. We checked the distributor and the module had oil between the plate we cleaned it and it is still doing it. It is over heating and we have done evwrything to try to fix the problem. I can bot afford to take it to a shop to be looked at and fixed. We are low income with three kids just trying to get by with what we got. The clutch needs to be replaced. It needs an ac compressor. This is the only car we have and I dont know what else to do. Im begging for help please if someone could please just point me in the right direction or find some kind hearted person to help out a family in need to get our car back un running order so we can get back and forth to work and the kids to school. It would be forever grateful. God bless
