Planning a wedding for my best friend

My best friend and her boyfriend are saving money for their future wedding. And I am going to help them, because she says: “I am going to planning my wedding, but I can’t only by myself. Help me, please!
They will search places for the reception and a photographer. They will choose invitations("receptions" is more common), a wedding dress, a wedding cake, decoration and more. I am going to help them with the decorations, like flowers, ceramic ware, cutlery and more.
They are going to invite only their closest family and friends, about 100 hundred people.
The wedding is going to be very expensive, but is their dream.

Solo algunos errores Lizzie, igual que en el post anterior, los marqué con azul y corregi con color rojo. Saludos! :)
