Needing help after huge vehicle mistake.

I am a disabled 53-year-old who wanted to get a smal car. Somebody said go to the auto auction. Okay so the vehicle drives in mind you somebody's behind the wheel driving it in I bid on it you want it when I went to pick it up and no longer starts. No I did do my research on this vehicle before purchase I knew it needed an alternator but I did not know that they had some machine under the hood that made it drive for them. In any event I don't know what I should do with it I don't know who would take a mechanic's special because once the alternator is fixed it would be quite a large score, but I don't have mechanics as friends or I don't know anybody who toes vehicles I just don't know what to do and I'm stuck without a car and without my money. But live and learn right. Does anybody out there that knows anything near the Hillsboro area that can help me out and let me know what I should do with this vehicle I thank you in advance.
