Photoshop forehead of face

My friends brother deceased away and since he was special child, he did not have much pics of his so I just one pic of him which he really likes so that I can gift him for a loving memory. I just have few pics of him to help you out. No amount of money can match the love but I just $20 as I am student so please help me out and I need the pic asap. You do not have to be perfect at it
