Help a poor college kid fix his car.

Hi my name is Eli. Im going to school for Advanced Electrical Engineering. I hope to build Highend audio gear for the masses. However I need to drive to school and work. I work a minimum wage job and dont make enough money to pay for my bills and fix my car. It needs a wheelbearing, an upper intake kit, spark plugs and wires, it weeps oil from the rear valve covers, and the alternator came of its mount in my driveway. It sheered one bolt and lost the other. It obviously a high milelage vehicle lol. Its a 99 Buick Park Avenue with 250,875. I can do all the work. Anything helps.  Thanks for looking.   P.> if your a car guru out there looking at this, dont worry the engine is pretty healthy for its age and the transmission doesnt make any noise. The 3800 engine is bulletproof (for the most part) So it's a worthy investment lol. Anyway thanks again all.
