Fundraising for grandma

On Monday morning my grandma passed away, and due to shock my grandad had a heart attack. He is now back at home but life will be very different for him now. He has been caring for my grandma for a number of years due to her health issues, so he must be feeling pretty lost without her. He is now in the process of organising her funeral, and my heart breaks that I can't do anything to help ease his pain. But I have an idea that I think will help him to see that grandma may not be here on earth, but she's in heaven and will always be with him. I need your help to achieve this though so I'm begging you!!! Anything you can spare will be hugely appreciated. Once i hit my target goal, anything left over will go to my grandad to help him out with any costs he has coming up. Thank you!
