Artificial eucalyptus, river rocks (Greenbelt)

Hello all! I am looking to retrieve a large batch of artificial eucalyptus flowers if anyone has some! I usually am asked by family to be responsible for decorating tables and my cousins bday is coming up where we are doing a Girl cousins spa day! I’m hoping someone has some and or some river rocks (preferably natural brown palette or black) I would greatly appreciate it and am mobile for the pick up! Thanks in advance!
