Mechanic Job in Phoenix, Arizona

Hi. I desperately need a very cheap mechanic basically willing to give me some of their valuable time. I have been stranded in phoenix from cottonwood (up north) since my car broke down. It is a 2003 Dodge Neon 2.0 and is parked near 35th ave and union hills drive. I can do some mechanic work and have tried every everything I can think of. It started with a bad radiator and went downhill from there. Its been sitting about a month now. It was doing the crank, no start. I was lucky to find same vehicle in a junkyard close by. So I can get parts cheap. When i exha usted all my funds, i started looking for help with local charitied/agencies. I posted an ad for a free (pro bono) mechanic on craigslist. I got 2 replies. Neither one came through. My last hope is through a close-by church that helps stranded people get back home. I am supposed to talk with them tomorrow. (Monday). I need to be able to tell them what is wrong with the car along with an estimate. The woman told me they would probably give me $200 toward the mechanic. So that will be all I can pay you. I would need a truly free estimate and not one that would be added later to the bill. And a mechanic who will fix my car for $200. I can help you do whatever you need done. I can go to the junkyard for parts of whatever. I just need to get home soon! Please help a broke girl out! Karma will repay you twofold. Thanks! Sue
