Well a place to start is pull off the belt and spin the Idler, Tensioner, AC, Alternator, and Power steering, Smog pump (if equipped) pulleys all should spin easy with no noise. Does the sound go away or change when turning on the AC? Also start the car with the belt off to make sure the noise is not coming from the motor. If noise go's away then it has to be one of the items I mentioned above. Cost will be depending on location and type of part gone bad.
Either your oil needs to be changed but most importantly The clearance in the connecting rod bearing have more clearance then tolerances allow. This could be due in part of low oil pressure. The gauge might show safe pressure but a manual gauge would give an accurate pressure. Hope this helps.
