Memorial area for my children to remembe their Dad

I would like to create a small area in our family home garden where the children can sit and fondly remember their Dad who sadly passed away on Friday. The garden will be filled with things the children remember from their childhood. It will have a handmade bench and table as Karl preferred things like that. Unfortunately I can't do this all by myself. Any help would be so amazing. I will keep people up to date once the garden starts taking shape and when it's  finished i will let people know what we have done with the funds.
