Hearing aids for my Dad

My dad has slowly lost his hearing over the last eight years. He's been an amazing role model and I'd love to help get his hearing back. He Is a good Christian man and truly loves everyone. He Is an amazing guy just doesn't make a lot of money. He worked for the same construction company for 20+ years then a couple years ago they closed up shop. He is back working but not nearly as much money as he was making. Please help me get his hearing back.
