Help my sister get married.

Hi everyone i am trying to raise funds for my sister and her fiance to get married as it is a wish of our very ill grandfather to see her get married before he passes away. She was raised by our grandparents since the age of 18months and is now 25years old and not once has she left their sides to live her own life so she means so much to them both, My sister and her finance weren't going to get married till they were financially ready but our grandfathers health isn't improving and it would mean the world to us if he gets to see her walk down the aisle.

Any donation is much appreciated.
